Abstract

Hydrogen disproportionation, desorption, and recombination (HDDR) has been used as a pretreatment to prepare high performance Sm₂Fe ₁₇N_x and NdFe₁₀Mo₂N_x compounds. Isotropic Sm₂Fe₁₇N_x and NdFe ₁₀Mo₂N_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.
