Laser powder bed fusion based CuCrZr alloy lattices: fabrication and characterization
Within this project, we will use an infra-red laser beam source based selective powder melting to fabricate copper alloy (CuCrZr) architectures. The focus will be on identifying the process parameter-microstructure-mechanical property relationships in 3-dimensional CuCrZr alloy lattice architectures, under both quasi-static and dynamic loading conditions.
Laser Powder Bed Fusion (LPBF) is the most commonly used Additive Manufacturing processes. One of its biggest advantages it offers is to exploit its inherent specific process characteristics, namely the decoupling the solidification rate from the parts´volume, for novel materials with superior physical and mechanical properties. One prominet example are so called High Modulus Steels, where the combination of strong, ductile and tough metallic matrices with stiff ceramic particles allows the specific modulus (E/ρ) to be increased compared to conventional materials such as aluminum or steel, thereby reducing weight. The aim of this project is to elucidate the synthesis/microstructure/property causalities of high modulus steel fabricated with the LPBF process. more
