摘要
NdFeB permanent magnets of(BH)_(max)=41MGOe were prepared by powder metallurgy.A typical specimen,Nd16.4Fe76.6B7 alloy,was measured and analyzed.The crystallization process of this alloy near 1400K appeared very complicated.Non-uniform distribution of Nd atoms in the alloy shows that a second phase may exist.At low temperatures the easy direction for magnetization will become canting.
