摘要	The precipitation behavior, mechanical properties, and strengthening mechanisms of FeCrNi-based medium entropy alloys fabricated by laser powder bed fusion and followed by aging treatment were investigated. Yield strength of the aged (FeCrNi)94Ti3Al3 alloy increases significantly from 993 to 1487 MPa, which is correlated to the strengthening effect of the co-existing several methods of hardening. Theoretical analyses demonstrate that coherent L12 nanoparticles formed within the face-centered cubic matrix contributes most of the improved strength for the aged (FeCrNi)94Ti3Al3 alloy, whereas recovery during aging cause the decrease of dislocation density thus exerts a softening effect. The results suggest the significant potential of precipitation strengthening for adjusting mechanical properties in alloys produced through laser powder bed fusion.
