[279] Significant enhancement of coercivity of hot-deformed magnets by two-step diffusion process
using a minimal amount of Dy
Keywords:permanent magnet、hot-deformed magnets、Nd-Fe-B、coercivity、remanence
This work demonstrated 2.5 T class coercivity can be achieved by the 2step diffusion process using a small amount of Dy without alloying Dy in the starting material.
