Abstract:

The microstructure of platelike Nd-Fe-B alloys prepared by rapid quenching from the melt, namely, by the strip casting technique, has been studied. The processes of grain refinement, texture formation, and sintering were optimized. It is shown that the maximum energy product (BH)(max) a parts per thousand yen 50 MGOe can be realized in sintered magnets prepared from the alloy with 29 wt \% Nd after a two-step heat treatment. The oxygen content in such magnets does not exceed 0.3 wt \%; the degree of texture is alpha(t) = 0.95.
