Swaging was investigated as a fabrication process for high-density Zn-bonded Sm-Fe-N magnets, which mainly consisted of Sm2Fe17Nx, and their magnetic properties were investigated. The demagnetization curves of the annealed specimens with or without swaging suggested that swaging improved the magnetic polarization. The specimen swaged with a reduction ratio (R) of 82%, a high maximum energy product ((BH)(max)) of 67.8 kJ.m(-3) with a high coercivity (H-cJ) of 1.89 MA.m(-1) was obtained. Sm-Fe-N particles were pulverized and the dispersion of Zn particles was improved during swaging, the density of specimens increased resulting in the increase in H-cJ and (BH)(max).
