 This study provides a review of the microstructures and mechanical properties of three metallic alloys processed by additive manufacturing, AM, highlighting the impact of AM on microstructure development, process microstructure property relationships and phase selection in high entropy alloys. The study uses property maps to compare the mechanical properties of additive manufactured alloys with conventionally processed counterparts.
