Abstract

A requirement for improving powder metallurgy technology of alloys for permanent magnets containing rare-earth metals based on the use of secondary resources and a replacement of rare-earth metals and fine control of the semifinished products chemical composition is demonstrated. These approaches are realized successfully in the preparation of Nd–Fe–B system magnetically hard materials by a binary mixture method using rare earth metal hydrides and their alloys. Analysis of the magnetic properties of Sm–Co–Cu–Fe–Zr system permanent magnets according to the results of the primary ingot chemical composition control minimizes production costs.
