| Abstract Scope |
New generation motors and electronic components that are more compact and efficient require soft magnetic materials that are well-balanced in their magnetic, electrical, and mechanical properties. Low-cost Fe-6.5%Si can be a great candidate due to its decreased magnetocrystalline anisotropy, near-zero magnetostriction, and increased electrical resistivity compared to conventional silicon steel. Not surprisingly, there is a surging demand for this 6.5 silicon steel with increased saturation magnetization and processability without compromising its high electrical resistivity. Through novel compositional design and high throughput experiments, we have investigated phase formation, magnetic saturation, iron losses, electrical resistivity, mechanical properties, and processability by investigating multiple Fe-Si-X systems (X = B, Co, etc.). This talk reviews the current state of the art in the compositional design of silicon steel and discusses our current development of Fe-Si-X alloys.
