Casting is a manufacturing process in which a liquid metal is poured inside a mold where it solidifies. The application of a magnetic field during the casting process which interacts with the thermoelectrical current generated by the temperature gradient produces electromagnetic forces and thus, convection in the melt. As a function of the magnetic field (…)
Non-metallic inclusion formation in iron-based alloys are an inevitable consequence of the steel production process. Although the inclusion content of commercial steels is reduced to around 0.1 wt.%, the detrimental effects of inclusions on the alloy mechanical properties are still present. Oxide inclusions are formed during the deoxidation process of steel, which consists of adding (…)
Ce projet de semestre porte sur l’étude de la densification de poudres de titane. La problématique à résoudre est de comprendre la cinétique de densification de ces poudres. Différentes voies d’études sont possibles et adaptables selon les souhaits de l’étudiant.Une analyse expérimentale peut être menée par méthode de frittage classique : pré-compaction de poudres et série (…)
Non-metallic inclusions, such as oxide, sulphides and nitrides, are commonly found in steels as a direct result of the steel-making process. Despite representing a small percentage of the steel’s composition, inclusions can have a significant influence on the mechanical properties of steel. The structure and composition of non-metallic inclusions in steels are a direct consequence (…)
Additive manufacturing (AM) consists of the fabrication of parts layer-by-layer. The most common AM processes to build metallic parts use high energy source such as a laser, an electron beam or a plasma to solidify powder. This allows the manufacturing of complex and bespoke geometries; however, the high-power consumption of these energy sources generates an (…)
