摘要

A study of the processing of HDDR powder with the composition Nd_(12.7)Fe_(81.3)B_(6.0) and Nd_(12.2)Fe_(81.2)B_(5.9)Zr_(0.1) have been undertaken. The homogenized alloys were disproportionated at 850°C for 30 minutes and employing a range of recombination temperatures from 790°C to 920°C. The optimum recombination temperature in the HDDR treatment was found to be 880°C. Zr-addition appears to inhibit grain growth during the treatment process.
