Influence of alloying elements on the mechanical properties of FeCo–V alloys

‘More electric aircraft’ technology necessitated improving the high temperature mechanical properties of FeCo–V alloys while maintaining their excellent magnetic properties. FeCo–2V alloys offer the highest saturation magnetization but do not meet the yield strength and creep resistance requirements. The aim of this paper is to review the influence of alloying elements, which enhance the mechanical properties without sacrificing the magnetic properties. Our alloy developmental efforts resulted in new FeCo–V alloys with unique combination of high tensile strength, good creep resistance and high electrical resistivity.
