On the structural, microstructural and magnetic properties evolution of Ni0.5FeCoAlCrx alloys

Abstract

The multicomponent alloy CoFeNiAlCr has shown great promise as a soft magnetic material due to its small coercive field and high saturation magnetisation at room temperature. By changing the ratio of the components, the Curie temperature can be tuned, along with improvements in both the coercive field and saturation magnetisation. The alloy system is interesting as the ratio of Al to Cr determines whether a single solid phase or a dual phase alloy is formed. This work has investigated the effects of Cr addition on the structural and magnetic properties of CoFeNi0.5AlCrx. It discusses the evolution of the NPs-matrix segregations and its constituents’ phases.
