The effects of melting processes on the resultant microstructure were studied. The results show that the grain of Cu-11Ni-2W alloy prepared by vacuum non-consumable arc-melting is coarse and the microstructure includes α solid solution and W particles. As for the sample prepared by high-frequency induction melting injection moulding, the grain is superfine and the microstructure is α solid solution. Moreover, the thermal conductivity coefficient for the sample prepared by vacuum non-consumable arc-melting is 67.2 W/(m•K), while that for high-frequency induction melting injection moulding is 47.8 W/(m•K).

Abstract:

Carbon-bonded silicon carbide and clay-bonded graphite crucibles are used in non-ferrous induction melting furnaces. Silicon carbide crucibles especially have encountered premature failure when used at high power densities and operating frequencies. This is thought to be related to their non-uniform properties. To gain a more thorough understanding of the problem, an equivalent circuit analysis has been applied to the composite load of crucible and metal charge.

Full text

Abstract:

Mg-PSZ refractories used as vacuum induction melting crucibles are particle-reinforced composites with aggregate and matrix phases comprising fused zirconia. Three commercial varieties were cycled eight times to service temperatures and their microstructural and thermomechanical evolution investigated, with focus placed on the aggregate populations. Two refractories, with large aggregates of similar size, were found to retain stiffness after cycling but in the refractory containing aggregates with high stabiliser levels, reaction between the stabiliser and Al and Si impurities produced secondary phases. Volume changes accompanying formation of these phases, and subsequent thermal expansion mismatches, led to aggregate break-up with consequent reductions in refractory toughness and strength. Secondary phases developed only rarely in the aggregates (with lower levels of stabiliser) of the second refractory. These aggregates remained intact and the refractory retained its toughness and strength. A third refractory contained small, unstabilised aggregates in a stabilised matrix and the strain mismatches that ensued during polymorphic transformation damaged microstructural interfaces. Refractory stiffness halved within eight cycles and toughness and strength were lost. All three refractories displayed R-curve behaviour and quasi-stable fracture curves were observed during bend tests. The study shows that when using fused zirconia aggregates to design refractories, engineers need to i) limit stabiliser concentrations - a difference of just ± 1 wt% Mg (in the presence of impurity elements) may determine whether secondary phase formation occurs and ii) eliminate alumina and silica impurities when possible through substitution of zircon sand with baddeleyite as the source for fused zirconia.

Abstract:

Recycling has proven not only to address today’s economical, environmental and social issues, but also to be imperative for the sustainability of human technology. The current thesis has investigated the feasibility of a new philosophy for Recycling (Alloying-Recycling) using steel 1020 and aluminum 6061T6. The study was limited to the metallurgical aspects only and has highlighted the potential of recycled alloys made of recycled aluminum and steel to exhibit substantially increased wear resistance and strength-to-weight ratio as compared to initial primary materials. Three alloy-mixtures are considered: TN3 (5wt% 1020 +95wt% 6061T6); TN5 (0.7wt% 1020 + 99.3wt% 6061T6); and TN4 (10wt% 6061T6 + 90wt% 1020). A Tucker induction power supply system (3kW; 135-400 kHz) is used to melt the alloy mixtures for casting in graphite crucibles. Heat treatment of the cast samples is done using a radiation box furnace. Microscopy, Vickers hardness and pin-on-disc abrasive wear tests are performed. Casting destroyed the initial microstructures of the alloys leading to a hardness reduction in the as-cast and solution heat-treated aluminum rich samples to 60 Hv from 140 Hv. Ageing slightly increased the hardness of the cast samples and provided a wear resistance two times higher than that of the initial 6061T6 material. On the steel rich side, the hardness of the as-cast TN4 was 480 Hv, which is more than twice as high as the initial hardness of steel 1020 of 202 Hv; this hints to strong internal and residual stress, probably martensite formation during fast cooling following casting. Solution heat treatment lowered the hardness to the original value of steel 1020, but provided about ten (10) times higher wear resistance; this suggests higher ductility and toughness of normalised TN4 as compared to 1020. In addition, TN4 exhibits about 25% weight reduction as compared to 1020. The actual recycling process and the effect of non-metallic impurities shall be investigated in future works. Also, the casting and heat treatment processes need to be improved.

Full text

Abstract:

Dans le procédé PIVIC, ayant pour objectif le conditionnement de déchets nucléaires technologiques mixtes, un bain de métal et de verre est maintenu en fusion par induction électromagnétique. La conductivité électrique du verre étant relativement faible, les forces de Laplace et le chauffage par effet Joule sont uniquement actifs dans le métal. Le verre est donc mis en mouvement et maintenu en fusion par son contact avec la phase métallique, ce qui complexifie le pilotage du procédé, notamment lorsque ce matériau commence à figer. L’objectif de cette thèse est d’étudier le couplage magnéto-thermo-hydrodynamique dans le procédé afin de comprendre le mécanisme à l’origine du figeage du verre et ainsi de pouvoir l’éviter. Pour ce faire, divers outils de modélisation numérique sont utilisés afin de représenter les phénomènes thermiques, hydrodynamiques et électromagnétiques dans le procédé.Un point crucial à prendre en compte est la déformation de la surface du métal par la pression magnétique, ce qui créé un dôme pouvant émerger de la phase de verre. Dans un premier temps, les transferts thermiques sont écartés pour la modélisation numérique. Le modèle développé consiste en un couplage entre COMSOL Multiphysics® (induction EM) et ANSYS Fluent® (mécanique des fluides en régime turbulent). Afin de représenter la déformation des interfaces entre les fluides, une formulation triphasique du modèle Volume Of Fluid (VOF) a été utilisée. Les résultats numériques obtenus sont comparés aux mesures effectuées sur le prototype du procédé. Cette étude met en évidence les paramètres ayant un impact important sur l’élaboration ainsi qu’un phénomène d’entrainement d’air entre les deux liquides.Dans un second temps, les phénomènes thermiques sont ajoutés au modèle numérique. Un modèle spécifique est développé pour représenter le rayonnement au niveau de la surface libre des liquides tout en utilisant le modèle VOF. La répartition des flux de refroidissement ainsi que la température dans le creuset obtenues avec ce modèle plus complet sont comparées avec le prototype. L’impact de la masse de verre dans le creuset sur le comportement thermique du procédé est finalement étudié
In the PIVIC process, aimed to package mixed technological nuclear wastes, a metal-glass bath is melted by electromagnetic induction. The electrical conductivity of the glass being relatively low, the Lorentz forces and the Joule heating are present only in the metal. The glass is therefore put in motion and heated by its contact with the metallic phase, which complicates the control of the process, especially when this material starts to freeze. The goal of this thesis is to study the magneto-thermo-hydrodynamic coupling in the process to understand the freezing mechanism in order to avoid it. To this end, several numerical modelling tools are used in order to represent the thermal, hydrodynamic, and electromagnetic phenomena in the process. An essential point to take into account is the deformation of the metal’s free surface by the magnetic pressure, producing a dome that can emerge from the glass phase.For the first stage of the numerical modelling, the heat transfers are discarded. The model developed consists in a coupling between COMSOL Multiphysics® (EM induction) and ANSYS Fluent® (turbulent fluid flow). In order to represent the deformation of the interfaces between the fluids, a three phase Volume Of Fluid (VOF) model is used. The results of the numerical model are compared to the measures performed on the prototype of the process. The study highlights the parameters having the most impact on the process and also raises an air entrainment phenomenon between the liquids.At the second stage, thermal phenomena are added to the numerical model. A separate model is developed to represent radiative heat transfers at the free surface of the liquids with the VOF model. The repartition of the cooling fluxes and the temperature inside the crucible are compared between this numerical model and the prototype. Finally, the impact of the glass mass in the crucible on the thermal behavior of the process is studied

Abstract:

Ce travail, qui s'inscrit dans le thème général de la maitrise des interactions métal liquide-réfractaire-atmosphère, a consiste à modéliser les transferts de matière et la précipitation inclusionnaire lors de l'élaboration au four à induction sous vide du Marphy 17. Le mouvement engendré par l'action des forces de brassage est calculé à l'aide d'un modèle qui résout également les équations de transports des différents solutés (ca, al, mg, o, c) par diffusion, convection et turbulence. Une attention particulière est portée au phénomène de volatilisation à la surface libre. La validation du modèle hydrodynamique est réalisée dans un four pilote à partir de comparaisons entre les déplacements d'une particule posée à la surface et le mouvement calculé du liquide. Les simulations mettent en évidence l'importance d'un calcul précis de l'intensité de la turbulence à la surface libre du bain métallique. Le modèle de transfert de matière, pour sa part, a permis de simuler des expériences de volatilisation du manganèse dissous dans le fer liquide. En couplant le modèle de transfert de matière à un modèle d'équilibre thermodynamique développe a l'IRSID, il est possible d'obtenir au cours du temps et en tout point du bain la composition du métal liquide ainsi que la composition et la nature des inclusions formées. Cette modélisation permet également de représenter, de manière simplifiée, les transferts de matière aux interfaces métal liquide-réfractaire. Les principaux résultats obtenus à l'aide de cette démarche sont présentés et discutées

Abstract:

A demanda por energia fotovoltaica vem aumentando a razão de mais de 20% ao ano no mercado internacional nos últimos dez anos. O silício com pureza entre 99,999% e 99,99999% é utilizado na fabricação de células fotovoltaicas. O silício metalúrgico tem pureza entre 98,5% e 99%. Este estudo visa investigar o refino a vácuo como um processo alternativo de menor custo para se obter o silício para células fotovoltaicas. Este processo pode remover o fósforo do silício, que é um dos elementos prejudiciais à célula fotovoltaica. Isso permitiria agregar valor à produção brasileira de silício metalúrgico, que alcança um preço de aproximadamente US$2,5 por quilo, enquanto o silício para células fotovoltaicas varia entre US$20 e 60 por quilo. Foram realizados experimentos de fusão em forno de indução a vácuo, variando parâmetros como temperatura, tempo e pressão. O teor de fósforo caiu de 33 ppm para cerca de 0,1 ppm e os resultados foram comparados com um modelo matemático da literatura. Conclui-se que o refino por este processo é tecnicamente viável.
The demand for photovoltaics is increasing at a ratio over 20 % per year in the international market in the last ten years. Silicon with purity of 99.999 % and 99.99999 % is used in the manufacture of photovoltaic cells. The purity of metallurgical silicon is between 98.5% and 99%. This study aims to investigate the vacuum refining process as a lower cost alternative to obtain silicon for photovoltaic cells. This process can remove phosphorus from silicon, which is a harmful element to the photovoltaic cell. This would add value to Brazilian production of metallurgical silicon, that reaches a price of approximately U.S.$ 2.5 per kilogram, while the silicon for photovoltaic cells varies between U.S.$ 20 and 60 per kilo . Melting experiments were performed in a vacuum induction furnace by varying such parameters as temperature, time and pressure. The phosphorus content dropped from 33 ppm to about 0.1 ppm and the results were compared with a mathematical model from literature. It is concluded that refining of this process is technically feasible.

Abstract:

Prezentovaná práce se zabývá vakuovým indukčním tavením intermetalické slitiny Ti-46Al-7Nb (at. %) v žáruvzdorných kelímcích na bázi Y2O3. Byla provedena série taveb pro teploty přehřátí taveniny 1630, 1680 and 1730 C a při různých dobách výdrže na této teplotě v rozmezí 5 až 30 minut. Ze slitin ztuhlých v tavících kelímcích byly připraveny metalografické výbrusy, které sloužily k hodnocení mikrostruktury a vyhodnocení složení fází. Pro získání těchto dat byly použity metosy elektronové mirkoskopie SEM a EDS. Kvantitativní hodnocení mikrostruktury, zejména obsahu oxidické faze ve slitině, bylo provedeno pomocí software Adaptive Contrast Control (ACC). Analýza obsahu kyslíku ve ztuhlé slitině byla provedena metodou IGF (fúze v inertním plynu). V této práci jsou pochody na rozhraní slitina/oxidický kelímek posuzovány také z termodynamického hlediska a to s použitím aktivit jednotlivých složek v systému. Data prezentovaná v této práci mohou být použita pro nastavení a optimalizaci procesů tavení intermetalik TiAlNb.

Abstract:

A number of additive manufacturing processes were analyzed and compared in regards to the direct 3D printing of copper induction coils. The purpose of this study was to narrow in on 3D printing technologies that would best be suited for the manufacture of copper inductions coils. The main focus of the study was to look at how all the available additive processes could specifically be successful at creating parts made of copper pure enough to effectively conduct electricity and also geometries complex enough to meet the demands of various induction coil designs. The results of this study led to three main categories of additive manufacturing that were deemed good choices for producing copper induction coils, these included: powder bed fusion, sheet lamination, and directed energy deposition. Specific processes identified within these categories were powder bed fusion using electron beam melting and laser melting; ultrasonic additive manufacturing; and directed energy deposition utilizing laser melting and electron beam melting using both wire and powder material delivery systems. Also discussed was additional benefits that using 3D printing technology could provide beyond the physical manufacturing portion by opening doors for coupling with computer aided drafting (CAD) and computer aided engineering (CAE) software in order to create a seamless design-to-production process.

Abstract:

Cold crucible induction melter (CCIM) technology has been widely used in melting of non-metallic refractory materials with a high melting point and a requirement of high purity. This paper discusses the application of the CCIM technology in melting of reactor corium (simulated as zirconium oxide in this experiment). In this experiment, the power supply is set at constant power control mode, with a design frequency of ∼100 kHz and a total output power of ∼ 400 kW. The cold crucible consists of copper tubes and a stainless bottom plate which has a dimension of 220 mm in diameter and 420 mm in height. The crucible is charged with zirconium oxide (ZrO2) powder and surrounded by a set of water-cooling induction coils which is designed shorter than the crucible in order to reduce energy loss in the water-cooling bottom plate. The top of the crucible and the coils are at the same height. A Zirconium ring is used to initiate heating process. ∼ kg ZrO2 powder is used for each experiment. Electrical variables of the induction melter and temperature of the melt are detected and recorded in the entire heating process. For the result, almost 3/4 of the ZrO2 powder is melt and a thin crust (∼ 2–3 mm) is generated between the melt and the crucible. To be specific, the ZrO2 powder above the bottom of the induction coils is melt, but others are not. In the melting process, the maximum surface temperature of the melt has reached 2230°C. Furthermore, for better understanding of the relationship between the melting process and the changing process of the electrical variables, an equivalent circuit of the heating system is established and analyzed. It can be concluded that some electrical variables such as the quality factor (Q) of the induction coils and the practical frequency can reflect melting status. The conclusion is confirmed by the records transmitted by sensors in the melting process. By comparison between the recorded data and the melting status, it is clear that the Q value can be accurately used in indicating the melting status due to its obvious change in the entire melting process. As the melting pool becoming larger, the Q value tends to be smaller. In contrast, the practical frequency becomes higher as the melt becoming larger. Furthermore, both of them are not influenced by the output power. In addition, the output current and the output voltage also can be used to describe the melting status. In specific, a larger melting pool corresponds to a lower output current and a higher output voltage.

Abstract:

The melting treatment is suitable for reducing the volume of the wastes because of the high volume reduction ratio (the volume reduction ratio is the initial volume to the volume after treatment). We have developed a new high-frequency induction melting system for the low-level radioactive miscellaneous solid wastes. The non-conductive ceramic canister and a heat loss compensator (Active insulator) were used in this new system. It is difficult to melt a large amount of the non-metallic materials with the canister. We solved this problem by using the active insulator, which was made of the conductive material. Melting performance confirmation tests were performed in the medium-scale melting system. Based on the result of the medium-scale melting test and multi-dimensional thermal-hydraulic analysis, the full-scale melting system was designed and constructed. We performed the melting tests using the full-scale melting system. the volume ratio of the non-metallic wastes at the re-solidification was more than 70%. Behavior of nuclides was also investigated with non-radioactive Co and Cs tracers. The residual ratio of Co and Cs were 97%, 58%, respectively.
