Abstract:
Multicomponent materials containing a comparatively large number of different elemental components, yet exhibiting simple crystal structures have opened up a new era of materials design with the possibility of tuning properties of materials with greater degrees of freedom. This poses a formidable challenge in terms of design as the number of parameters involved in simulating such systems increase significantly with the increasing number of components. This work reports a sampling methodology based on hybrid genetic algorithm-molecular dynamics for sampling positional-disordered materials such as high-entropy systems. This investigation also demonstrates the influence of individual cationic species on the evolution of distortion in single-phase solid solution with the rock-salt structure, when oxides such as CoO, CuO, MgO, NiO and ZnO are mixed together. Additionally, the relationship between the number of atomic species and its effect on the lattice distortion has been presented. The influence of alloying elements on the evolution of lattice friction in substitutional alloys has been studied using Monte Carlo simulations with a continuum elasticity relation for dislocations. The spread in energy-range due to elastic properties and size-misfit of elements provides physical justification for friction stress being low in CoNi alloy, high in CoCrNi (medium entropy alloy), along with intermediate values in CoCrFeNi (High Entropy Alloy). A similar approach justifies strengthening due to dilute addition of Al into CoCrFeMnNi and CoCrFeNi. This approach is a computationally cheap method of screening a range of possible alloys with respect to their lattice friction stress. Spin-polarised density functional theory (DFT) calculations presented here were carried out to study the charge transfer among elements and evolution of distortion in substitutional alloys. To study the characteristics of the individual element, impurity-in- matrix type calculations were carried out. The charge transfer between impurity and matrix element is presented to determine issues with the electronegativity parameter of Miedema’s model for enthalpy calculations. The distortion in substitutional alloys, particularly due to Cr has been found to be related to interaction of electrons with complementary spins in their d-orbitals.

Abstract:
This PhD thesis is a part of the Accelerated Metallurgy (AccMet) project funded under the Seventh Framework Programme. AccMet’s aims consists on the delivery of an integrated pilot-scale facility for the combinatorial synthesis and testing of those unexplored material. The contribution of this thesis to AccMet has been expanded in 3 years while focused in the understanding and development of a methodology suitable for the combinatorial synthesis of novel materials, and particularly of High Entropy Alloys (HEAs). These novel materials are composed of multiple elements at near equiatomic levels with the capacity of forming simple crystalline phases such as bcc and fcc instead of the expected intermetallic compounds as well as their excellent combination of structural and functional properties compared to the traditional materials. A mathematical technique known as Principal Component Analysis has been used here to identify patterns within a set of metallic systems forming a wide range of crystalline structures. This technique would not only speed up the compositional design stage but also contribute to the development of a virtual library containing all the explored systems. Mercury Centre has been an important key during the synthesis of HEAs where Spark Plasma Sintering (SPS) and Electron Beam Melting (EBM) have been successfully applied for the development of the thesis. The final combination of the design stage, production and characterisation of HEAs developed in this thesis would result in an advances technique suitable not only for the synthesis of novel HEAs, but also for the discovery of other unexplored systems.

Abstract:
High entropy alloys (HEAs) is a concept wherein alloys are constructed with five or more elements mixed in equal proportions; these are also known as multi-principle elements (MPEs) or complex concentrated alloys (CCAs). This PhD thesis dissertation presents research conducted to develop precipitation-hardenable high entropy alloys using a much-studied fcc-based equi-atomic quaternary alloy (CoCrFeNi). Minor additions of aluminium make the alloy amenable for precipitating ordered intermetallic phases in an fcc matrix. Aluminum also affects grain growth kinetics and Hall-Petch hardenability. The use of a combinatorial approach for assessing composition-microstructure-property relationships in high entropy alloys, or more broadly in complex concentrated alloys; using laser deposited compositionally graded AlxCrCuFeNi2 (0 < x < 1.5) complex concentrated alloys as a candidate system. The composition gradient has been achieved from CrCuFeNi2 to Al1.5CrCuFeNi2 over a length of ~25 mm, deposited using the laser engineered net shaping process from a blend of elemental powders. With increasing Al content, there was a gradual change from an fcc-based microstructure (including the ordered L12 phase) to a bcc-based microstructure (including the ordered B2 phase), accompanied with a progressive increase in microhardness. Based on this combinatorial assessment, two promising fcc-based precipitation strengthened systems have been identified; Al0.3CuCrFeNi2 and Al0.3CoCrFeNi, and both compositions were subsequently thermo-mechanically processed via conventional techniques. The phase stability and mechanical properties of these alloys have been investigated and will be presented. Additionally, the activation energy for grain growth as a function of Al content in these complex alloys has also been investigated. Change in fcc grain growth kinetic was studied as a function of aluminum; the apparent activation energy for grain growth increases by about three times going from Al0.1CoCrFeNi (3% Al (at%)) to Al0.3CoCrFeNi. (7% Al (at%)). Furthermore, Al addition leads to the precipitation of highly refined ordered L12 (γ′) and B2 precipitates in Al0.3CoCrFeNi. A detailed investigation of precipitation of the ordered phases in Al0.3CoCrFeNi and their thermal stability is done using atom probe tomography (APT), transmission electron microscopy (TEM) and Synchrotron X-ray in situ and ex situ analyses. The alloy strengthened via grain boundary strengthening following the Hall-Petch relationship offers a large increment of strength with small variation in grain size. Tensile strength of the Al0.3CoFeNi is increased by 50% on precipitation fine-scale γ′ precipitates. Furthermore, precipitation of bcc based ordered phase B2 in Al0.3CoCrFeNi can further strengthen the alloy. Fine-tuning the microstructure by thermo-mechanical treatments achieved a wide range of mechanical properties in the same alloy. The Al0.3CoCrFeNi HEA exhibited ultimate tensile strength (UTS) of ~250 MPa and ductility of ~65%; a UTS of ~1100 MPa and ductility of ~30%; and a UTS of 1850 MPa and a ductility of 5% after various thermo-mechanical treatments. Grain sizes, precipitates type and size scales manipulated in the alloy result in different strength ductility combinations. Henceforth, the alloy presents a fertile ground for development by grain boundary strengthening and precipitation strengthening, and offers very high activation energy of grain growth aptly suitable for high-temperature applications.

Abstract:
In this dissertation, tribo-corrosion behavior of several single-phase and multi-phase high entropy alloys were investigated. Tribo-corrosion of body centered cubic MoNbTaTiZr high entropy alloy in simulated physiological environment showed very low friction coefficient (~ 0.04), low wear rate (~ 10-8 mm3/Nm), body-temperature assisted passivation, and excellent biocompatibility with respect to stem cells and bone forming osteoblast cells. Tribo-corrosion resistance was evaluated for additively manufactured face centered cubic CoCrFeMnNi high entropy alloy in simulated marine environment. The additively manufactured alloy was found to be significantly better than its as-cast counterpart which was attributed to the refined microstructure and homogeneous elemental distribution. Additively manufactured CoCrFeMnNi showed lower wear rate, regenerative passivation, less wear volume loss, and nobler corrosion potential during tribo-corrosion test compared to its as-cast equivalent. Furthermore, in the elevated temperature (100 °C) tribo-corrosion environment, AlCoCrFeNi2.1 eutectic high entropy alloy showed excellent microstructural stability and pitting resistance with an order of magnitude lower wear volume loss compared to duplex stainless steel. The knowledge gained from tribo-corrosion response and stress-corrosion susceptibility of high entropy alloys was used in the development of bio-electrochemical sensors to sense implant degradation. The results obtained herewith support the promise of high entropy alloys in outperforming currently used structural alloys in the harsh tribo-corrosion environment.

Abstract:
High-entropy alloys (HEAs) are composed of multi-principal elements with equal or near-equal concentrations, which open up a vast compositional space for alloy design. Based on first-principle theory, we focus on the fundamental characteristics of the reported HEAs, as well as on the optimization and prediction of alternative HEAs with promising technological applications. The ab initio calculations presented in the thesis confirm and predict the relatively structural stability of different HEAs, and discuss the composition and temperature-induced phase transformations. The elastic behavior of several HEAs are evaluated through the single-crystal and polycrystalline elastic moduli by making use of a series of phenomenological models. The competition between dislocation full slip, twinning, and martensitic transformation during plastic deformation of HEAs with face-centered cubic phase are analyzed by studying the generalized stacking fault energy. The magnetic moments and magnetic exchange interactions for selected HEAs are calculated, and then applied in the Heisenberg Hamiltonian model in connection with Monte-Carlo simulations to get further insight into the magnetic characteristics including Curie point. The Debye-Grüneisen model is used to estimate the temperature variation of the thermal expansion coefficient. This work provides specific theoretical points of view to try to understand the intrinsic physical mechanisms behind the observed complex behavior in multi-component systems, and reveals some opportunities for designing and optimizing the properties of materials

Full text
Abstract:
An investigation into the phase transformation of metastable alloys such as high entropy alloys (HEAs) and high entropy bulk metallic glasses (HE-BMGs) was performed. Bulk metallic glasses (BMGs) and HEAs were known to have a metastable phase at high temperature, while HEAs was reported to have a sluggish diffusion at high temperature. Besides, the drawback of many single phase HEAs is that they are mechanically unstable due to the presence of single phase either body centred cubic (BCC) or face centred cubic (FCC) structures. Here, a systematic study on the crystal structure, physical and mechanical properties of TiZrHfNiCu HE-BMG and FeCoNi(BxAl1-x)0.1Si0.1 (0 ≤ x ≤ 1) lamellar structured HEA were explored. It was revealed that, a phase transformation occurred in HE-BMG in isothermal and non-isothermal conditions, yet the nucleation and growth behaviour was relatively slow at high temperature compared to most Zr-based amorphous alloys. This phenomenon was proven by the attained data of activation energy and crystallisation mechanism which reflect the crystallisation resistance of the alloy. The addition of boron as a substitution of aluminium in FeCoNi(BxAl1-x)0.1Si0.1 alloy changed the phase formation, phase stability, morphology characteristics and mechanical properties of the alloy. The unique lamellar herringbone-like structure was formed with increasing boron content and led to improvement of mechanical properties of the alloy such as the hardness from B0.4 to B1.0. Lamellar structured-HEA was designed to obtain a balance in strength and ductility for FeCoNi(Bx Al1-x)0.1Si0.1 HEA where it can be tailored by modifying the boron content. The optimum balance of strength (1550 MPa) and ductility (19%) was attained at 0.5 at% boron content.

Abstract:
The novel class of alloys known as high entropy alloys (HEAs) present two fundamental problems; 1) prediction of their properties and reaction to alloying adjustments, 2) prediction of compositions capable of forming the random solid solution with simple crystal structure that appears to be key to their behaviour. Here DFT is applied to model the electronic structure of HEAs based on the CoCrFeNi pseudo base metal. This approach explains a number of properties such as preferred crystal structure and allows fundamental properties such as elastic moduli to be calculated accurately. The stability of HEAs is discussed and compared to that of bulk metallic glasses and a composition is produced which is capable of forming both a glassy and high entropy solid solution phase. A simple thermodynamic model is proposed to allow likely HEA solid solution forming compositions to be identified. This modelling approach using both DFT and thermodynamics is used to assess two potential high entropy alloys based on light metals. The approach shows that the electronic structure of HEAs may be used to predict their properties and therefore their behaviour is due to a free electron structure, it also suggests that the most important consideration in their stability as solid solution alloys is a lack of strong covalent interactions, ie a close to zero entropy of mixing.

Abstract:
Les Alliages à Haute Entropie (AHEs ou HEAs en anglais) sont un nouveau type d'alliages multi-élémentaires. Ils contiennent au moins cinq éléments de teneur comprise entre 5 et 35 at %. L'entropie de configuration élevée, qui est une raison du nom de cette famille d'alliages, ainsi que d'autres paramètres, tels que l'enthalpie de mélange, la différence de taille atomique, la différence d'électronégativité ou la concentration d'électrons de valence, stabilisent une solution solide plutôt que des composés intermétalliques. L'attention de la communauté scientifique a été attirée par les propriétés prometteuses et les microstructures intéressantes des HEAs.Dans ce travail, une nouvelle famille de HEAs Al-Cr-Fe-Mn-Mo a été étudiée. Les analyses microstructurales et chimiques ont été menées par DRX, spectrométrie Mössbauer, MEB, MET, EDX, EBSD. Dans un premier temps, des calculs basés sur une approche paramétrique ont été réalisés pour optimiser la composition chimique. Les compositions sélectionnées ont été préparées par mécanosynthèse dans différents types broyeurs. Les conditions optimisées garantissant une homogénéité chimique maximale de la poudre et une faible contamination par les matériaux des billes et des jarres ont été déterminées. Deux phases cubique centrée (cc) se forment pendant la mécanosynthèse avec les paramètres de maille 3,13 Å (cc#1) et 2,93 Å (cc#2). Le traitement thermique de la poudre entraîne plusieurs transformations de phase (la formation de la phase χ). Le recuit à 950 °C/1 h favorise l'augmentation de la fraction volumique de la phase cc#2, tandis que les cc#1 et χ disparaissent. Néanmoins, de petites fractions de carbures et d'oxydes ont été trouvées.Les échantillons massifs ont été fabriqués par frittage à chaud des poudres mécanosynthétisées. Les conditions de consolidation ont été évaluées et optimisées pour favoriser la formation de la phase cc et réduire la formation de carbures et d'oxydes résultant de la contamination. Les échantillons massifs optimisés présentent une phase majoritaire cubique centrée (> 95 % volumique) avec un paramètre de maille de 2,92 Å et une très petite quantité de carbures (M6C, M23C6) et d'oxydes (Al2O3). La phase cc est stable après recuit à 950 °C pendant 10 h. De plus, l'alliage présente une dureté très élevée jusqu'à 950 HV2N. Les essais de compression de l'échantillon massif optimisé, entre la température ambiante et 800 °C, révèlent des propriétés prometteuses, en particulier entre 600 et 700 °C. L'alliage présente un comportement fragile entre la température ambiante et 400 °C. Cependant, l'alliage commence à démontrer un certain degré de plasticité à 500 °C. À 600 °C, la limite d'élasticité est de 1022 MPa, tandis que la déformation à la rupture est d'environ 22 %
High Entropy Alloys (HEAs) are a new type of multicomponent alloys. They contain at least five elements with the content of each between 5 and 35 at. %. The high configuration entropy, which is the source of the name of the whole family of alloys, together with other parameters, such as mixing enthalpy, atomic size difference, electronegativity difference, or valence electron concentration, stabilize a solid solution instead of complex intermetallic compounds. Promising properties and interesting microstructures focus the attention of the scientific community to HEAs.In this work, the novel Al-Cr-Fe-Mn-Mo high entropy alloy family was studied. The microstructural and chemical analyses were performed by XRD, Mössbauer spectrometry, SEM, TEM, EDX, EBSD. In the first stage, parametric approach calculations were carried out to optimize the chemical composition of the alloy. The selected compositions were prepared by mechanical alloying in different devices. The optimized conditions that ensure maximum chemical homogeneity of powder and the small contamination from balls and vial materials were chosen. In most of the powders, two bcc phases form during mechanical alloying with the lattice parameters about 3.13 Å (bcc#1) and 2.93 Å (bcc#2). The heat treatment of powder results in several phase transformations (e.g., the formation of the χ phase). The annealing at 950 °C for 1 h promotes the significant increase of volume fraction of the bcc#2 phase, while the bcc#1 and χ disappear. Nevertheless, small fractions of carbides and oxides were found. The bulk samples were fabricated by hot press sintering of the optimized mechanically alloyed powders. The conditions of consolidation were evaluated and optimized to promote the formation of the bcc phase and reduce the formation of carbides and oxides resulting from the contamination during mechanical alloying and sintering. The optimized bulk samples present a major disordered body-centered cubic phase (> 95 % of volume fraction) with a lattice parameter of 2.92 Å and a very small fraction of carbides (M6C, M23C6) and oxides (Al2O3). The bcc phase is stable after annealing at 950 °C for 10 h. Moreover, the alloy presents very high hardness up to 950 HV2N. The compression tests of the optimized bulk sample from room temperature to 800 °C reveal promising properties, especially between 600 and 700 °C. The alloy shows brittle behavior between room temperature and 400 °C. However, the alloy starts to demonstrate some degree of plasticity at 500 °C. At 600 °C, the yield strength is 1022 MPa, while strain to failure is about 22 %

Abstract:
High entropy alloys (HEAs) based on refractory elements have shown a great potential for high temperature structural applications. In particular, the ones containing Al, exhibits a microstructure similar to the γ-γ' in Ni-based superalloys. While these alloys exhibit impressive strengths at room temperature (RT) and at elevated temperatures, the continuous B2 matrix in these alloys is likely to be responsible for their brittle behavior at RT. Phase stability of five such alloys are studied by thermo-mechanical treatments and characterization techniques using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Two of these alloys showed an inverted microstructure, where the disordered BCC phase becomes continuous, and therefore, they were characterized in detail using SEM, TEM, atom probe tomography (APT) and synchrotron x-ray diffraction experiments. The phenomenon of phase inversion lead to a better combination of strength and ductility as compared to the non-inverted microstructure.To enhance the stability of B2 intermetallic phase which provides the strength when present in a BCC matrix, multicomponent B2 phase compositions stable at 1000°C in some of the above studied alloys, were melted separately. The aim was to establish a single phase B2 at 1000°C and understand the mechanical behavior of these single-phase multicomponent B2 intermetallic alloys. These alloys exhibited a ductile behavior under compression and retained ~1 GPa yield strength at temperature up to 600°C. The ductile nature of these alloys is attributed to the change in bonding nature form directional to metallic bonding, possibly resulting from a significantly high configurational entropy compared to binary or ternary stoichiometric B2 compounds.

Abstract:
This paper presents ongoing research at NETL aimed at gaining fundamental understanding of high-entropy alloys (HEAs) formation and their properties, and developing highperformance HEAs for high-temperature fossil energy applications. First-principles density functional theory (DFT), Monte Carlo simulation, and molecular dynamics simulation are carried out to predict enthalpy of formation, the entropy sources (i.e., configurational entropy, vibrational entropy, and electronic entropy), and elastic properties of model single-phase HEAs with the face-centered cubic, body-centered cubic and hexagonal closed-packed structures. Classical elastic theory, which considers the interactions between dislocations and elastic fields of solutes, has also been used to predict solid solution strengthening. Large-size (∼7.5 kg) HEAs ingots are produced using vacuum induction melting and electroslag remelting methods, followed by homogenization treatment resulting in greater than 99% homogeneity. Subsequent thermomechanical processing produces fully-wrought face-centered cubic microstructures. The tensile behavior for these alloys have been determined as a function of temperature, and based on these results screening creep tests have been performed at selected temperatures and stresses.
