Abstract

Recent investigations using rare earth containing alloy Elektron®MAP+43, which is an atomized alloy powder specifically developed for additive manufacturing (A/M)based on the Elektron®43 composition with a nominal composition of Mg-4Y-3Zr, have shown that it is possible to achieve near-theoretical densities using both laser directed energy deposition and laser powder bed fusion process. Mechanical properties obtained compare favorably with cast and heat treated WE43 alloy. However, to develop a robust process for magnesium-based powders, several aspects need to be considered including identifying suitable particle size distribution, build strategies, metal vaporization and condensation, and interaction of laser with the powder, to name a few. The processing details, microstructure, and mechanical properties for Elektron®MAP+43 process via A/M are presented in this paper.
