The Printability, Microstructure, and Mechanical Properties of FeMnCoCr High-Entropy Alloys Fabricated by Laser Powder Bed Fusion Additive Manufacturing.

This work investigated the effect of Fe/Mn ratio on the microstructure and mechanical properties of non-equimolar FeMnCoCr ( = 30% and 50%) high-entropy alloys (HEAs) fabricated by laser powder bed fusion (LPBF) additive manufacturing. Process optimization was conducted to achieve fully dense FeMnCoCr and FeMnCoCr HEAs using a volumetric energy density of 105.82 J·mm.
