FIELD: powder metallurgy, in particular, manufacture of high-coercive field permanent magnets based on alloys of rare-earth-metals such as iron-boron. ^ SUBSTANCE: method involves producing alloy-admixture based on niobium-cobalt system containing 10-15 wt% of cobalt; grinding each alloy for obtaining of powder; providing mixing and fine milling of powders; introducing alloy-admixture at fine milling stage in an amount of 0.1-0.2 wt%; compacting resulted mixture in magnetic field and caking. Method allows caked magnets to be produced, said magnets having high coercive field and insignificantly reduced magnetic induction. ^ EFFECT: increased efficiency in producing of high-coercive field magnets. ^ 5 cl, 1 dwg, 1 tbl |
