Abstract
Hydrogen disproportionation, desorption, and recombination (HDDR) has been used as a pretreatment to prepare high performance Sm2Fe17N x and NdFe10Mo2N x compounds. Isotropic Sm2Fe17N x and NdFe10Mo2N x compounds with intrinsic coercivity larger than 12 and 4 kOe have been obtained by nitriding the HDDR treated powders, respectively. It is found that the magnetic properties are sensitively dependent on the time and temperature of the HDDR process, which determine the grain size, nitrogen content, and the amount of α‐Fe in the nitrides.This publication has 1 reference indexed in Scilit:
