Abstract
Hydrogen disproportionation, desorption, and recombination (HDDR) has been used as a pretreatment to prepare high performance Sm2Fe17Nx and NdFe10Mo2Nx compounds. Isotropic Sm2Fe17Nx and NdFe10Mo2Nx compounds w ith intrinsic coercivity larger than 12 and 4 kOe have been obtained b y nitriding the HDDR treated powders, respectively. It is found that t he magnetic properties are sensitively dependent on the time and tempe rature of the HDDR process, which determine the grain size, nitrogen c ontent, and the amount of alpha-Fe in the nitrides.
