Anisotropic HDDR-treated Nd2Fe14B-type powder

Effects of the wheel speeds v and disproportionation time during the SC-HDDR process on the properties of Nd-Fe-B magnetic powders are investigated. It is found that the remanence B r , coercivity H cj and energy products ( BH ) max of magnetic powders all first increase to the maximum at v =3 m/s,...
