While there has been substantial effort focused on additive manufacturing of structural alloys over the past couple of decades, there have been rather limited efforts on AM of functional alloys, such as magnetic materials. The present study will focus on laser additive processing of magnetic alloys using the laser engineered net shaping (LENS) process that falls under the category of directed energy deposition processes. Fe, Co, and Ni based soft magnetic alloys have been processed using LENS system. The LENS technique can be effectively used to process compositionally-graded alloys by systematically varying the flow rates from individual powder hoppers that comprise the feedstock. Influence of Fe/Co ratio and B2 ordering on the magnetic properties of as-deposited alloys, and heat treated Hiperco type soft magnetic alloys will also be discussed in this presentation. This work shows the feasibility of AM in processing of soft magnetic materials.
