Tailoring RE-rich phase migration to suppress Ce-induced microstructural degradation in hot-deformed Nd-Fe-B magnets

Key Points

• Microstructural degradation is reduced significantly when tailoring phase migration strategies.
• Results indicate that adjusting the phase migration process leads to a decrease in Ce-induced degradation effects.
• Assessment using tailored phase migration in hot-deformed Nd-Fe-B magnets revealed key changes in structure.
• Highlights the importance of phase migration in enhancing the stability of Nd-Fe-B magnets under stress.
