Abstract
This paper presents new results of an investigation of a commercial rapidly quenched Nd4.5Fe77B18.5 alloy that was studied previously. The enhanced remanence Jr = 13.2 KGs and high product energy (BH)max = 16.2 MGOe are shown to be due to ultrafine grain. The microstructure, consisting of no alpha-Fe that results in optimum magnetic properties, occurs in the amorphous Nd4.5Fe77B18.5 alloy after crystallization. The coexistence of Fe3B, Nd2Fe14B and residual amorphous phase play dominant roles in the achievement of the hard magnetic properties, and hence, the amorphous phase seems to act as an effective magnetic exchange-coupled medium.
