摘要：

The magnetic properties and the microstructure of Nd-Fe-B and Nd-Fe-Co-Ga-B die upset magnets produced from amorphous materials were studied. The Nd-Fe-B die upset magnets had fine polygonal Nd2Fe14B grains and showed magnetic anisotropy. The compositional modification and optimization of the die upset condition led to the increase in the remanence and coercivity values of the Nd-Fe-B die upset magnets. The optimally deformed Nd-Fe-Co-Ga-B die upset magnets showed the maximum energy product of 54.4 MGOc. (C) 1998 American Institute of Physics. [S0021-8979(98)15011-9].
