Abstract Scope

Nd-Fe-B permanent magnets are essential for high-performance motors in electric vehicles, with their magnetic properties closely tied to solidification quality. During strip casting, solidification forms T1, FCC, and Nd-rich phases, which influence the subsequent hydrogen decrepitation process used to isolate T1 grains. Precise control of solidification is thus critical for maximizing the yield of high quality T1 grains. This study employs a phase-field model to simulate microstructural evolution during strip casting of stoichiometric Nd-Fe-B alloys. By analyzing various process conditions, we identify key factors affecting phase formation and propose optimized parameters to enhance T1 phase development, supporting improved magnetic performance.
