Influence of a static magnetic field on the solidification of cast Al-Cu alloys
Casting is a manufacturing process in which a liquid metal is poured inside a mold where it solidifies. Applying a magnetic field during this casting process will lead to the interaction of a magnetic field with a thermoelectrical current generated by the temperature gradient alog the liquid/solid interface, thus, producing electromagnetic forces. These in turn (…)
Experimental (1 student) and simulation (1 student) of the temperature distribution within a nozzle from a 3D printer
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 (…)
Synthesis and nanoindentation of calcium-silicate inclusions in iron
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 (…)
Solid state processing of ceramic-reinforced metal-matrix composites
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 steelâs 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 (…)
Tensile testing of Ti6Al4V / C&TiC composites produced by Electro-Sinter Forging (already assigned)
The goal of this semester project is to measure the tensile properties of composites produced by an ultrafast sintering technique called Electro-Sinter Forging (ESF). ESF is a process in which the combination of a pressure pulse and an electrical discharge produce the sintering of electrically conductive powder preforms. It is very energetic and ultrafast (less (…)
Influence of Mg additions on the microstructure and composition of oxide inclusions in iron-based alloys
Non-metallic inclusions, including oxide, sulphides and nitrides, are commonly found in steels as a direct result of steelmaking and thermal treatment processes. Despite representing a small percentage of the steelâs composition, inclusions have a significant influence, generally detrimental, on the mechanical properties of steel. The structure and composition of non-metallic inclusions in steels are a (…)
Effet du taux dâoxygĂšne sur les propriĂ©tĂ©s mĂ©caniques dâĂ©chantillons de titane produits par frittage ultra-rapide (dĂ©jĂ assignĂ© Ă un Ă©tudiant)
Dans ce projet de semestre, lâĂ©tudiant aura lâopportunitĂ© dâĂ©tudier des Ă©chantillons de titane de diffĂ©rents niveaux de puretĂ© commerciale produits par un nouveau procĂ©dĂ© de frittage ultra-rapide : Grade 2, Grade 3, Grade 4. La diffĂ©rence entre ces grades se porte surtout sur la teneur en atomes dâoxygĂšne en position interstitielle. Le but de ce (…)
Processing and thermal treatment of oxide inclusion containing carbon steels
Controlling the composition, size and microstructure of oxide inclusions, whose presence is practically unavoidable in steels, is a major goal within the steelmaking industry. It is well known that the amount and type of non-metallic inclusions have a direct influence on the physical and mechanical properties of steel properties like strength, fatigue, ductile-brittle fracture, welding, (…)
Study of the interaction of various build plate materials with deposited liquid aluminium (already assigned to a student)
Additive manufacturing (AM) consists of the fabrication of parts layer-by-layer or point-by-point. The most common AM processes designed to build metallic parts use high energy sources such as a laser, an electron beam or a plasma, generally to melt and solidify powder. This allows the manufacturing of complex and bespoke geometries; however, the high-power consumption (…)
