| Abstract Scope |
Equiatomic Fe-Co alloy exhibits maximum saturation magnetisation along with high electrical resistivity and good magnetic permeability which render this alloy suitable for use in high power-density electrical applications. However, the significant brittleness of the alloy makes it difficult to process through traditional metal processing routes. Addition of 2 wt.% V is added to Fe-Co alloy improves the ductility but also reduces the magnetic saturation by 5-8%.
Wire-arc additive manufacturing (WAAM) of equiatomic Fe-Co alloy has been attempted using a cold-wire-fed plasma arc torch coupled with a CNC manipulator. Special attention was paid to preventing the vertical cold cracking issue resulting in a completely crack-free deposit. A complete characterization of microstructure, tensile properties and B-H loop measurement was performed which revealed more than 95% saturation magnetisation as obtained in the current process. |
