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 and temperatures with low 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. Two alloy systems are explored, Co-based amorphous and nanocrystalline alloys for high temperature applications and Fe-based amorphous alloys for line frequency applications, modifying variations in glass former elements and ferromagnetic transition metals to evaluate the effects on (1) high temperature magnetic and microstructural stability, (2) glass forming ability, (3) saturation magnetization, and (4) magnetostriction. Through systematic compositional design and post-processing, we identify stable, manufacturable alloys with improved magnetic and structural properties. This framework enables accelerated optimization of soft magnetic materials for diverse applications. |
