Abstract

Ni-Fe-Mo/V known as Permalloys are of great interest because of widespread applications in transformers, electric motors, and other electromagnetic devices. This letter focuses on the ability to utilize laser-based additive manufacturing, specifically the laser engineered net shaping (LENS™) process, to deposit soft magnetic Ni-Fe-V and Ni-Fe-Mo alloys. Though these alloys have been deposited from an elemental powder blend, they exhibit relatively uniform fcc solid solution microstructures. While the saturation magnetization (M_s) values for the LENS™ deposited alloys is comparable to those of their conventionally processed counterparts, the laser processed alloys exhibit higher coercivity (H_c) values, presumably due to microstructural defects.
