Project Overview
E-machine manufacturing has experienced significant growth over the past five years, with projections indicating continued expansion. Improved efficiency can be achieved by design and materials optimization. Currently most e-machines utilize standard electrical steels (approx. 3 wt% Si grades) with materials choices for high-frequency motors being Fe-Co alloys (expensive but used for aerospace) and 6 wt% Si electrical steel (single supplier, expensive, non-sustainable production route). Therefore, there is an opportunity to develop improved electrical steels, produced using conventional mass production processing, for widespread use in e-machines that will directly enhance battery range but also facilitate the redesign of motors, resulting in further motor efficiency improvements.
At WMG, we have developed a new novel grade of electrical steel, based on conventional processing, with significantly superior properties (approx. 40% improvement is magnetic efficiency and 33% improvement in strength). This PhD will therefore focus on developing an understanding on composition-processing-property performance in a novel steel in the context of considering how this alloy could be manufactured using the current commercial processing route. The key academic questions will therefore include:
How does the microstructure evolve throughout processing and does a difference in stacking fault energy, caused by compositional modification, change the propensity for defects (for better or for worse)?
We are excited to push this new alloy to market and make real impact.
