研究了用非晶材料制备的Nd-Fe-B和Nd-Fe-Co-Ga-B模具镦粗磁体的磁性能和显微结构。Nd-Fe-B模具镦粗磁体具有细小的多边形Nd 2Fe 14 B晶粒，并表现出磁各向异性。通过对Nd-Fe-B合金成分的改进和模具镦锻工艺条件的优化，提高了Nd-Fe-B合金的剩磁和矫顽力。最佳变形的Nd-Fe-Co-Ga-B模具镦锻磁体显示出54.4 MGOe的最大能量积。
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 MGOe.
