| Abstract Scope |
Amorphous and nanocrystalline soft magnetic alloys are of interest to high efficiency distribution transformers as well as power electronics operating at high frequencies with low core losses. Their performance can be tailored through compositional and processing adjustments, but their complex, multicomponent nature makes property prediction challenging. This work introduces a combined strategy using statistical modeling, thermodynamic simulations, and experimental validation to guide alloy development of Fe-based amorphous alloys for line frequency applications. Variations in glass former elements and ferromagnetic transition metals are explored to evaluate their effects on glass forming ability, saturation magnetization, and magnetostriction. Planar flow casting parameters are independently optimized to ensure stable, high quality amorphous ribbon production. Through this coupled composition and process design approach, we identify manufacturable alloys with improved magnetic and structural properties, enabling accelerated optimization of soft magnetic materials for diverse applications. |
