摘要：

The coercivities of directly quenched nanophase (Nd-Pr)-Fe-B alloys are intermediate between those of their Nd- and Pr-based counterparts. Jr and (BH)max, however, show maxima at a Nd:Pr ratio 1:3. Doping with 1 at% Zr results in significant grain refinement and an increased anisotropy constant, which leads to useful improvements in magnetic properties for most of the directly quenched nanophase alloys in the series Nd alloys. Excellent combinations of (BH)max and iHc are attained by the overquench and anneal route for nanocrystalline single phase Pr12(FeCo)82B6 alloys.
