Life Cycle Assessment of Direct Liquid Metal Deposition
Additive manufacturing (AM) consists of the fabrication of parts layer-by-layer. The most common AM processes 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 of these energy (…)
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. The application during the casting process of a magnetic field which interacts with the thermoelectrical current generated by the temperature gradient produces electromagnetic forces that alter convection patterns in the melt. As a function of the magnetic (…)
“What is inside?” – Mapping TiC precipitates within electro-sinter forged titanium matrix composites
The goal of this semester project is to characterize the three-dimensional structure of a two-phase system, sintered with an ultrafast sintering technique called ESF. ESF (Electro-Sinter Forging) is a process in which a combination of a pressure and an electrical pulse result in the sintering of the material. It is very energetic and ultrafast (less (…)
Master’s Project on Numerical Methods for Solidification Problems
In the context of a project on additive manufacturing, molten aluminum is fed vertically through a pipe and deposited at the exit onto a cold substrate moving in the horizontal direction, thus forming a free surface in air. Upon deposition, the liquid aluminum is cooled by the substrate and ultimately solidifies. Both the solidification front (…)
Processing and thermal treatment of manganese – silicate inclusion containing 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 due to their significant impact on the material’s physical, chemical, and mechanical properties. Understanding the influence of these inclusions on the steel requires detailed characterization of their local properties, including their (…)
Influence of the Surface Quality of Aluminium Wire on Porosity in Additively Manufactured Parts
Additive manufacturing for metals is a manufacturing process where powder, wire or filament is deposited or fused layer by layer to form a finished part of prechosen geometry. An additive manufacturing technology named Direct Liquid Metal Deposition (DLMD) is currently under development at LMM. Aluminium wire is fed through a nozzle and melted in order (…)
