Soft magnetic materials for aerospace applications

Abstract

This author collated and reviewed existing literature regarding soft magnetic materials, to better understand the materials suited for aerospace applications and compare the functionality and characteristics of these given materials. It is quickly clear that Fe-Co alloys are the most attractive candidates for usage in an electric engine, and review was narrowed to a focus on the aforementioned material. The consensus that followed was the observation that the Fe-Co-V ternary alloy would exhibit the most suitable attributes for the given application. This report then follows the different routes taken to improve the Fe-Co-V alloy and comparatively analyse the effectiveness of the different alloying elements and processing methods suggested in the relevant literature.
