 This paper reviews the microstructures and mechanical properties of three different metallic alloys produced through additive manufacturing, AM, processes. It focuses on the effect of AM processing on the microstructure and its relationship with mechanical properties. For titanium alloy T6L4V, the paper discusses how AM induces metallurgical defects and microstructures which affect mechanical properties. For steels, it examines the influence of surface roughness and build atmosphere on mechanical and damaged properties. Finally, it looks at the effect of rapid solidification on phase selection in high entropy alloys. The paper concludes by creating a visual summary of the mechanical properties of AM produced alloys, comparing them to those produced via conventional methods.
