| Abstract Scope |
While there has been substantial effort focused on additive manufacturing of structural alloys over the past few decades, there have been rather limited efforts on AM of functional alloys, such as magnetic materials. This 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. Soft and semi-hard magnetic binary and ternary alloys of different types comprising Fe, Co& Ni ferromagnetic elements have been processed using LENS. 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 and heat treated Hiperco type soft magnetic alloys will also be discussed in this presentation. This work shows the feasibility of AM processing of soft magnetic materials. |
