Thermal stability of HDDR processed Sm-Fe-Ti-B-N bonded magnets is investigated in comparison with HDDR processed Sm-Fe-N bonded magnets. Temperature coefficients of Br and iHc of Sm-Fe-Ti-B-N bonded magnet are -0.06%//spl deg/C and -0.43%//spl deg/C

Basic investigations to apply the rapid quenched Nd-Fe-B die-upset technique to fabricate trapezoid-shaped magnets with high energy product were undertaken. Stress around the magnets with indentations during die-upsetting was evaluated by computer si

The addition of Ga to Nd-Fe-B sintered and die-upset magnets in order to improve thermal stability was examined. The Ga addition increases the coercivity of Nd(Fe/sub 0.72/Co/sub 0.2/B/sub 0.08/)/sub 5.6/ sintered magnets markedly. Ga addition does n
