Abstract
Soft magnetic alloys produced by additive manufacturing (AM) typically exhibit inferior magnetic properties compared to conventionally processed counterparts. The present study shows that the saturation magnetization and coercivity of the equiatomic ternary CoFeNi complex concentrated alloy (CCA), processed using the laser engineered net shaping (LENS) additive manufacturing (AM) technique, is identical to that of conventionally cast and thermo-mechanically processed samples. Further, the LENS processed alloy exhibits higher yield strength and marginally lower ductility compared to conventionally processed alloys. LENS processed CoFeNi exhibited an excellent combination of soft magnetic and mechanical properties, relevant, e.g., to high speed electrical machines.
