Abstract 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.
