Abstract:
Phase diagram and thermodynamic data of 18 binary common-ion molten salt systems in Na,K,Ba//F,MoO4,WO4 were optimized by computer algorithm. The phase diagram data as well as single-salt data were retrieved from an extensive critical literature search. Expressions for the excess properties of solution phases and thermodynamic properties of intermediate compounds were thereby obtained. These data were used to generate a "best" phase diagram for each binary system considered. Key words: molten salts, phase diagrams, thermodynamic properties.

Abstract:
Emergence of a large variety of self-assembled superlattices is a dramatic recent trend in the fields of nanoparticle and colloidal sciences. Motivated by this development, we propose a model that combines simplicity with a remarkably rich phase behavior applicable to a wide range of such self-assembled systems. Those systems include nanoparticle and colloidal assemblies driven by DNA-mediated interactions, electrostatics, and possibly, controlled drying. In our model, a binary system of large and small hard spheres (L and S, respectively) interacts via selective short-range (“sticky”) attraction. In its simplest version, this binary sticky sphere model features attraction only between S and L particles. We show that, in the limit when this attraction is sufficiently strong compared with kT, the problem becomes purely geometrical: the thermodynamically preferred state should maximize the number of LS contacts. A general procedure for constructing the phase diagram as a function of system composition f and particle size ratio r is outlined. In this way, the global phase behavior can be calculated very efficiently for a given set of plausible candidate phases. Furthermore, the geometric nature of the problem enables us to generate those candidate phases through a well-defined and intuitive construction. We calculate the phase diagrams for both 2D and 3D systems and compare the results with existing experiments. Most of the 3D superlattices observed to date are featured in our phase diagram, whereas several more are predicted for future discovery.

Abstract:
The equilibrium phase diagram and thermodynamic properties of a mixture of drugs and additives are information related to various possible interaction processes between components. Therefore, we conducted a study of the phase diagrams and thermodynamic properties of binary mixtures of ketoprofen-succinic acid to estimate the types of interactions that may occur between these materials. The solid-liquid phase diagram of ketoprofen-succinic acid binary mixtures was determined by differential scanning calorimetry and composition of eutectic system was determined accurately using a Tamman diagram. The measurement of binary mixtures of ketoprofen-succinic acid with differential scanning calorimeter obtained the value of melting temperature and heat of fusion of ketoprofen- succinic acid system. The solid-liquid phase diagram of ketoprofen- succinic acid showed the formation of eutectic type phase diagram. The Tamman diagram showed accurately composition of the eutectic system of the Kp-SA binary mixtures at the mole fraction of Kp 0.87 and temperature 96.9oC.Keywords: ketoprofen, phase diagram, eutectic system, Tamman diagram

Abstract:
CALPHAD (CALculation of PHAse Diagram) is a useful tool to construct phase diagrams of various materials under different thermodynamic conditions. Researchers have extended the use of the CALPHAD method to nanophase diagrams and pressure phase diagrams. In this study, the phase diagram of an arbitrary A–B nanoparticle system under pressure was investigated. The effects of the interaction parameter and excess volume were investigated with increasing pressure. The eutectic temperature was found to decrease in most cases, except when the interaction parameter in the liquid was zero and that in the solid was positive, while the excess volume parameter of the liquid was positive. Under these conditions, the eutectic temperature increased with increasing pressure.

Abstract:
The solid-phase diagram of binary systems consisting of particles of diameter σA=σ and σB=γσ (γ≤1) interacting with an inverse p = 12 power law is investigated as a paradigm of a soft potential. In addition to the diameter ratio γ that characterizes hard-sphere models, the phase diagram is a function of an additional parameter that controls the relative interaction strength between the different particle types. Phase diagrams are determined from extremes of thermodynamic functions by considering 15 candidate lattices. In general, it is shown that the phase diagram of a soft repulsive potential leads to the morphological diversity observed in experiments with binary nanoparticles, thus providing a general framework to understand their phase diagrams. Particular emphasis is given to the two most successful crystallization strategies so far: evaporation of solvent from nanoparticles with grafted hydrocarbon ligands and DNA programmable self-assembly.

Abstract:
Welding is a non-equilibrium process. However, some weldability issues, as the extension of the heat-affected zone (HAZ) can be addressed using equilibrium phase diagrams. The 70 wt% Fe-Cr-Ni pseudo-binary phase diagram is commonly used to establish the phase transformations during welding of duplex stainless steels. The predicted results are assumed to be reasonably good for most of the duplex stainless steels. Thermodynamic calculations were used to determine multicomponent phase diagrams and volumetric fraction of phases present as a function of temperature several commercial duplex stainless steels. Results showed that simplified pseudobinary phase diagram approach is valid to estimate welded joint microstructures only for the low alloy duplex stainless steels as UNS S32304, but phase transformations and mainly solidification paths of high alloy duplex stainless steels should predicted only using a multi-component phase diagram.

Full text
Abstract:
Spinodal decomposition is a phase separation mechanism within the miscibility gap. Its importance in case of Fe-Cr system, the basis of the whole stainless steel family, stems from a phenomenon known as the “475oC embrittlement” which results in a ruin of mechanical properties of ferritic, martensitic and duplex stainless steels. This work is aimed at a better understanding of the phase separation process in   the Fe-Cr system. Alloys of 10 to 55 wt.% Cr , each five percent, were homogenized to achieve fully ferritic microstructure and then isothermally aged at 400, 500 and 600oC for different periods of time ranging from 30min to 1500 hours. Hardness of both homogenized and aged samples were measured by the Vickers micro-hardness method and then selected samples were studied by means of Transmission Electron Microscopy (TEM).  It was observed that hardness of homogenized samples increased monotonically with increasing Cr content up to 55 wt.% which can be attributed to solution hardening as well as higher hardness of pure chromium compared to pure iron.  At 400oC no significant change in hardness was detected for aging up to 1500h, therefore we believe that phase separation effects at 400oC are very small up to this time. Sluggish kinetics is imputed to lower diffusion rate at lower temperatures. At 500oC even after 10h a noticeable change in hardness, for alloys containing 25 wt.% Cr and higher, was observed which indicates occurrence of phase separation. The alloy with 10 wt.% Cr did not show change in hardness up to 200h which suggests that this composition falls outside the miscibility gap at 500oC. For compositions of 15 and 20 wt.% Cr only a small increase in hardness was detected even after 200h of aging at 500oC, which could be due to the small amounts of α´ formed. However, it means that alloys of 15 wt.% Cr and higher are suffering phase separation. For compositions inside the miscibility gap, hardening effect is a result of phase separation either by nucleation and growth or spinodal decomposition. To distinguish between these two mechanisms, TEM studies were performed and we found evidence that at 500oC the Fe-25 wt.% Cr sample decomposes by nucleation  and growth  while that of 35 wt.% Cr  shows characteristics of the spinodal mechanism. For compositions inside the miscibility gap, with increasing Cr content up to 40% the change in hardness generally increased and for 45% and higher it always decreased. This suggests that the composition range corresponding to the spinodal region at 500oC is biased towards the Fe-rich side of the phase diagram. At 600oC only samples of 25, 30 and 35 wt.% Cr were studied because according to the previous studies, the spinodal boundary is most probably located in this composition range. However, no change in hardness was observed even up to 24h. We believe that this means the miscibility line lies below 600oC for alloys containing 35 wt.% Cr and lower. Further investigations are needed to confirm and explain this result.

Abstract:
Les diagrammes de phases des n-alcanes consécutifs impairs (n-C21H44 : n-C23H48 et n-C23H48 : n-C25H52) sont établis en utilisant conjointement les analyses calorimétriques différentielles et la diffraction des rayons-X. Contrairement à ce qu'il est généralement admis dans la littérature, ces mélanges binaires de n-alcanes ne sont pas miscibles en toute proportion, mais forment aux basses températures des domaines de solutions solides primaires limitées et trois phases intermédiaires conformément à la règle phénoménologique des successions des phases solides dans les systèmes binaires de n-alcanes consécutifs (19 < n < 27) établie au laboratoire. Aux hautes températures deux domaines monophasés sont mis en évidence: la phase [Beta] (Fmmm) qui subit une transition ROTATOR RI du second ordre et la phase ROTATOR [Alpha]-RII (R3m) sous le solidus. Ces deux diagrammes sont similaires et permettent d'établir une systématique du comportement des mélanges binaires des n-alcanes impairs consécutifs. Des mesures expérimentales permettent de modéliser la variation de l'enthalpie des corps purs et des phases solides binaires, en utilisant une expression de type solide d'EINSTEIN pour les phases de basses températures et des fonctions linéaires pour celles de hautes températures. Les courbes limites de phases sont restituées par un calcul d'équilibre phase par phase, en appliquant aux fonctions thermodynamiques d'excès un modèle de type MARGULES. Les paramètres des diverses fonctions sont ajustés afin de garder une bonne cohérence dans le calcul global du diagramme, dans ce contexte les constantes d'excès sont identiques pour les phases isostructurales

Die vorliegende Arbeit liefert einen Beitrag zum Verständnis der komplexen Wechselwirkungen zwischen Nanopartikeln und Polymeren in dünnen Schichtsystemen. Dazu wurden in einem geeignetem Modellsystem drei verschiedene Einflussparameter auf die Nanopartikelverteilung im Polymer und zwischen einer hydrophilen und einer hydrophoben Grenzfläche analysiert. Für eine erste Abschätzung der Verträglichkeit der einzelnen Komponenten wurden Wechselwirkungsparameter, binäre und ternäre Phasendiagramme ermittelt. Die experimentelle Charakterisierung der Nanopartikelverteilung erfolgte mittels Rasterkraftmikroskopie, Rasterelektronenmikroskopie und Transmissionselektronenmikroskopie. Die erhaltenen Ergebnisse wurden mit denen der theoretischen Vorbetrachtungen verglichen um herauszufinden, ob Vorhersagen zur Nanopartikelverteilung in einem Polymer möglich sind. In dieser Arbeit konnte gezeigt werden, dass die Nanopartikelverteilung im Polymer mit den untersuchten Parametern gezielt beeinflusst werden kann.

Abstract:
Des dépôts de cristaux d'hydrocarbures, se forment dans les gazoles à basse température. Ceux-ci sont principalement constitués de n-alcanes qui forment entre eux des solutions solides. Pour prévoir cette cristallisation, il est nécessaire de connaitre les propriétés thermodynamiques des mélanges solides. Le but de ce travail est l'étude du système binaire de n-alcanes pairs n-tétracosane (n-C24H50): n-hexacosane (n-C26H54), dont le diagramme est incomplet. Après une description des méthodes expérimentales utilisées, et une revue bibliographique sur les n-alcanes purs et en mélanges binaires, le diagramme de phases n-tétracosane: n-hexacosane est établi expérimentalement par analyse thermique différentielle, enthalpimétrique différentielle et radiocristallographie. Il est mis en évidence à 293 K et en fonction de la concentration molaire en n-hexacosane, la présence de deux solutions primaires de structure triclinique et de trois solutions solides intermédiaires de structure orthorhombique. Le comportement des mélanges en fonction de la température fait apparaitre quatre ou cinq séquences de phases selon la solution solide considérée. Une systématique de diagrammes binaires de n-alcanes pairs différents de deux carbones est établie par analogie avec le système n-docosane (n-C22H46): n-tetracosane (n-C24H50) et le systeme n-eicosane (n-C20H42): n-docosane (n-C22H46). Le traitement des mesures enthalpimétriques est ensuite effectué. Les variations d'enthalpie en fonction de la température des solutions solides qui apparaissent à température ambiante sont traitées par une expression dérivée du solide d'EINSTEIN. Les enthalpies et les entropies d'excès, des différentes phases sont représentées par un modèle de MARGULES à deux termes. Celles-ci jointes aux températures et aux enthalpies de transition des corps purs permettent de calculer les courbes limites de phases des différents équilibres. Le diagramme ainsi calculé coïncide avec celui établi expérimentalement

Abstract:
Plus de 4000 exoplanètes ont été découvertes, orbitant autour d’étoiles ayant différentes compositions. Ces exoplanètes sont détectées et étudiées par observations indirectes qui, dans de nombreux cas, donnent accès aux propriétés principales des planètes: leurs masses et leurs rayons. Ces paramètres peuvent être calculés à partir d’un modèle et comparés à ceux observés. Toutefois, cela est plus difficile pour des planètes qui orbitent autour d’étoiles ayant une composition chimique différente du Soleil, par exemple enrichie en carbone, car les propriétés physiques des carbures (i.e. carbures de silicium ou de fer) sont inconnues. Dans cette étude les systèmes Si-C et Fe-Si-C ont été étudiés entre 20 et 200 GPa et 300-3000 K, en utilisant la diffraction de rayons x et l’analyse chimique des échantillons récupérés pour déterminer les propriétés physiques dans des conditions extrêmes. Dans le système Si-C les équations d’états et les modèles thermiques pour les deux phases de basse et haute pression ont été déterminés. Les résultats ont ensuite été utilisé pour calculer la relation masse-rayon de planètes synthétiques ayant un noyau de fer et un manteau de SiC. Concernant le système Fe-Si-C le diagramme de phase ternaire a été reconstruit. En faisant l’hypothèse d’une composition Fe-Si-C pour un noyau planétaire, quatre différentes séquences de cristallisation ont été démontrées, déterminant des comportements dynamiques très diffèrent. En conclusion la relation masse-rayon n’est pas suffisante pour déterminer la composition et la structure interne des exoplanètes observées mais des données relatives à la chimie du système planétaire sont requises
More than 4000 exoplanets have been discovered, orbiting around stars with a wide variety of composition. Such planets are detected and studied through indirect methods that in many cases give access to the main properties of the planets: mass and radius. The same parameters can be calculated from a chosen model and compared to the observed ones. However it is difficult for planets orbiting around stars with compositions very different from our Sun, for example carbon enriched, as the physical properties carbides (i.e. silicon carbides and iron carbides) at extreme pressure are unknown. In this work the Si-C and Fe-Si-C systems were studied in the range between 20 and 200 GPa and 300-3000 K employing X-ray diffraction and chemical analyses on the recovered samples were used to determine the physical properties at extreme conditions. In the Si-C system the equations of state and thermal model for both the low pressure and high pressure phases were determined. The results were then used to model a mass radius plot for different archetypal planets with a Fe core and SiC mantle. Regarding the Fe-Si-C system a ternary phase diagram was reconstructed up to 200 GPa and 3000 K. Assuming Fe-Si-C as main component of planetary cores, four different crystallization paths are individuated, giving rise to way different dynamical behaviour. We conclude that using only mass radius relations is not sufficient to determine the interior composition and structure of an observed exoplanet and further data relative to the chemistry are needed, for example the composition of the host star

Abstract:
Un alliage métallique complexe (CMA) est un composé intermétallique dont la maille élémentaire est constituée d’un nombre important d’atomes formant bien souvent des aggrégats de haute symmétrie. De la complexité de ces composés peuvent découler des propriétés physico-chimiques intéressantes pour divers domaines d’application. Le système binaire aluminium-iridium est un système qui présente de nombreux composés intermétalliques dont la moitié sont des CMA. Malgré l’étude approfondie dont ce système a fait l’objet dans la littérature, certaines incertitudes demeuraient irrésolues, nous amenant ainsi à réexaminer le diagramme de phase Al-Ir. Nous avons également exploré les systèmes ternaires dits "push-pull" Al-Au-Ir et Al-Ag-Ir, propices à la formation de phases CMA selon certains auteurs. Au total, une centaine d’échantillons ont été préparés par fusion à l’arc puis analysés par diverses techniques de caractérisations: diffraction des rayons X (XRD), microscopie électronique à balayage (SEM), analyse dispersive en énergie (EDS) et analyse thermique différentielle (DTA). Quatre nouveaux composés intermétalliques ont ainsi été identifiés: Al2.4Ir, Al72Au2.5Ir29.5, Al3AuIr et Al11SiIr6, ce dernier étant issu d’une manipulation accidentelle. La structure cristallographique de chacun de ces composés a été résolue, révélant Al2.4Ir et Al72Au2.5Ir29.5 comme étant des CMA possédant une centaine d’atomes dans la maille. Des calculs basés sur la théorie de la fonctionnelle de la densité (DFT) sont venus apporter des précisions concernant la stabilité des composés Al3AuIr et Al11SiIr6. Pour le système Al-Ir, une variante structurale de deux CMA déjà connus de la littérature a également pu être mise en évidence. Les structures cristallographiques de la variante de Al2.75Ir et de celle de Al28Ir9 ont ainsi été approchées, présentant 240 et 444 atomes dans leur maille respective. Les propriétés de surface comptent parmi les aspects les plus intéressants des CMA, par exemple pour la catalyse hétérogène. En l’absence de monocristaux de taille macroscopique, nous avons étudié la possibilité de former des composés de surface par dépôt de Ir sur une surface Al(100) suivi de recuits. Des caractérisations par diffraction d’électrons lents (LEED), spectroscopie de photoélectrons excités par rayons X (XPS) et microscopie à effet tunnel (STM) supportés par ces calculs ab initio ont révélé qu’à partir de 320°C, le composé Al9Ir2 se formait en surface mais également dans une partie du volume du substrat
A complex metallic alloy (CMA) is an intermetallic compound whose unit cell contains a large number of atoms oftenly forming highly-symmetric clusters. From the complexity of these compounds can arise physical and chemical properties interesting for various fields of application. The aluminium-iridium binary system exhibits numerous intermetallic compounds of which half of them are actually CMAs. Despite this system being extensively studied in the literature, some uncertainies remained unsolved, leading us to reinvestigate the Al-Ir phase diagram. In addition, the "push-pull" systems Al-Au-Ir and Al-Ag-Ir, favorable for the formation of CMA according to the literature, have been explored. Thus, near a hundred of samples have been prepared by arc-melting before being analyzed with different characterizations techniques: X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and differential thermal analysis (DTA). From this study, 4 new intermetallic compounds could be identified: Al2.4Ir, Al72Au2.5Ir29.5, Al3AuIr and Al11SiIr6, the latter being the result of a fortuitous manipulation. The crystallographic structure of each of these compounds has been solved, revealing Al2.4Ir and Al72Au2.5Ir29.5 to be two CMAs with around one hundred of atoms in their unit cell. Calculations based on the density functional theory (DFT) brought further details about the stability of the two other Al3AuIr and Al11SiIr6 compounds. In the Al-Ir binary system, a structural variant of two well-known CMAs has been also unveiled. The crystallographic structures of the Al2.75Ir and Al28Ir9 variant have been approached, revealing 240 and 444 atoms in their respective unit cell. The CMAs oftently exhibit interesting surface properties. In order to study the Al-Ir compound surfaces, iridium adsorption on Al(100) surface followed by annealing has been investigated. The characterizations by lowenergy electrons diffraction (LEED), X-ray photoelectron spectroscopy (XPS) and scanning tunneling miscoscopy (STM) supported by ab initio calculations revealed that, from 320 C, the Al9Ir2 compound is formed at the surface but also in the substrate bulk

Abstract:
To select a lead-free solder system, factors such as eutectic/peritectic point, electron negativity, abundance, cost, toxicity of elements, world production capacity, segregation during solidification, possibility to form low melting phases with Pb, among others must be carefully considered. On the basis of thorough analysis of binary phase diagrams of Sn-X-systems (X represents other elements) and the properties of the element X, the Sn-Co-Cu eutectic ternary alloy system has been chosen as a new lead-free solder candidate. In order to find the eutectic point for the Sn-Co-Cu system, the Sn-Co binary system was thoroughly assessed with CALPHAD (CALculation of PHAse Diagram) methods. The ternary phase diagram of Sn-Co-Cu system was extrapolated with the assessed thermodynamic parameters of Sn-Co, Sn-Cu, and Co-Cu system. The eutectic point for L–Sn2Co+(Sn)+Cu6Sn5 is 224.4°C and 0.37%Co and 0.68%Cu and 98.95%Sn.

Abstract:
Zirconium hydride block is an important hydrogen storage material which is used as moderator in space nuclear power reactor. The effect of temperature in the preparation of crackfree zirconium hydride was investigated in this work. The hydriding temperature curve including 3 key steps was designed based on the Zr-H binary phase diagram. The changes of hydrogen pressure with time were observed in the experiment and the hydrogen pressure dropped down when the temperature reached about 876 °C because of the β→δ phase transformation. The phase transformation step in the experiment contributed to the cracking control critically. The hydrogen content of the zirconium hydride was decided by the temperature of the last step.

Abstract:
This paper deals with the numerical calculation of an energy-recovering unit for air-conditioning and heat pump systems. Currently, working fluids are expanded in expansion valves in air-conditionings or, in general, refrigeration systems. The aim of this work is to increase the efficiency of the air-conditioning systems by replacing the irreversible nozzle with an energy recovering working machine. An air-conditioning system with a high enthalpy difference between inlet and outlet combined with a small volume flow is in the focus of the investigation in the presented study. According to the well-known Cordier diagram, a Pelton turbine with one nozzle is the most efficient machine for this purpose. One part of the investigation is the nozzle and the other is the Pelton wheel. The inlet conditions for the nozzle are supercritical and the pressure ratio is 2.3; the working fluid is CO2. During the expansion, the phase changes from supercritical to liquid and finally at the outlet two-phase flow is expected. The numerical calculations were executed with Ansys CFX 12. Two different numerical approaches — the homogeneous binary mixture and the Eulerian-Eulerian inhomogeneous multiphase model — are used. For the Eulerian-Eulerian calculation, the flow morphology is assumed to be polydispersed. Different bubble diameters are simulated with the MUSIG model. A comparison between the calculation with homogeneous binary mixture and Eulerian-Eulerian is presented as well. A parameter study about the nozzle, impeller and casing is performed which leads to the design point geometry. It will be shown that the optimal nozzle contour at design point conditions is converging - diverging although the flow is subsonic.

Abstract:
Head-on collisions of binary micro-droplets are of great interest in both academic research and engineering applications. Numerical simulation of this problem is challenging due to complex interfacial changes and large density ratio between different fluids. In this work, the recently proposed lattice Boltzmann flux solver (LBFS) is applied to study this problem. The LBFS is a finite volume method for the direct update of macroscopic flow variables at cell centers. The fluxes of the LBFS are reconstructed at each cell interface through lattice moments of density distribution functions (DDFs). As compared with conventional multiphase lattice Boltzmann method, the LBFS can be easily applied to study complex multiphase flows with large density ratio. In addition, external forces can be implemented more conveniently and the tie-up between the time step and mesh spacing is also removed. Moreover, it can deal with complex boundary conditions directly as those do in the conventional Navier-Stokes solvers. At first, the reliability of the LBFS is validated by simulating a micro-droplet impacting on a dry surface at density ratio 832 (air to water). The obtained result agrees well with experimental measurement. After that, numerical simulations of head-on collisions of two micro droplets are carried out to examine different collisional behaviors in a wide range of Reynolds numbers and Weber numbers of 100 ≤ Re ≤ 2000 and 10 ≤ We ≤ 500. A phase diagram parameterized by these two control parameters is obtained to classify the outcomes of these collisions. It is shown that, at low Reynolds number (Re=100), two droplets will be coalescent into a bigger one for all considered Weber numbers. With the increase of the Reynolds number, separation of the collision into multiple droplets appears and the critical Weber number for separation is decreased. When the Reynolds number is sufficiently high, the critical Weber number for separation is between 20 and 25.
