| Abstract Scope |
Higher Si (up to 6.5 wt%) contenting electrical steels possess favorable electrical and magnetic properties for the core of the induction motor rotors in electric vehicles. However, Si facilitates the formation of secondary ordered phases, making the alloy brittle and susceptible to cracking during the fabrication process, thus limiting mass production. This work examines the feasibility of friction stir processing (FSP) as a solid-state processing tool to improve the mechanical properties of the high Si-containing electrical steel while maintaining the desired magnetic and electrical response. FSP can modify the alloy microstructure without changing the composition. A variety of processing parameters like temperature, rotational speed, traverse speed, etc. are used to obtain samples at various conditions. Our study shows that processing temperature has a considerable effect on grain size. We also explore the effect of FSP parameters and subsequent microstructure on the mechanical, electrical, and magnetic properties. |
