Randomized trial evaluates the impact of Y on Dy diffusion in Nd-Fe-B magnets, suggesting enhanced magnetic performance.

This research aims to understand how yttrium affects dysprosium diffusion in Nd-Fe-B magnets and its influence on magnetic properties.
Single-source and co-diffusion treatments using DyHx and YHx through grain boundary diffusion processing
Evaluated grain boundary characteristics and magnetic performance with microstructural analyses
Focused on Nd-Ce-Fe-B magnets with 50% Ce mass substitution.
Coercivity of Nd-Ce-Fe-B magnets reached 13.58 kOe after co-diffusion, an enhancement of 1.55 kOe compared to DyHx-only treatment
Synchronous diffusion improved Dy penetration and distribution uniformity, forming a continuous Dy-rich shell
Coercivity for Nd-Fe-B magnets with co-diffusion was lower than that of DyHx-only diffusion.

WANG et al. (2026) studied this question.
