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