The current PhD project aims at finding solutions for the two major challenges that currently limit the wider use of copper based alloy parts manufactured by laser-based powder bed fusion (L-PBF): a) the availability of suitable starting powders with significant absorption at the current used laser wavelengths and b) the occurrence of cracks and pores in L-PBF processed Cu based parts due to the low laser absorption, high thermal conductivity and large residual stresses.

The project is aimed at a) improving the existing knowledge/understanding on the interaction of electromagnetic waves with Cu based pre-alloyed powders and b) understanding and steering the solidification behavior of both solid solution forming and precipitation strengthening Cu based alloys.
