On the mechanism of formation of high-coercive states in the nanostructured hard magnetic Fe-Cr-Co-based alloys

摘要

@@The hard magnetic dispersion-hardening alloys of Fe Cr-Co with the contents of 5-25 wt.% cobalt,20-40 wt.% chromium and alloying elements such as Al,Si,Nb,Ti,Mo,V,etc.in up to 5 wt.% were second opened after W.Koster [ 1 ] by Pr.H.Kaneko with staff in the early 70-ies [ 2 ]. They have found industrial ap plication for production of permanent magnets from the mid 80-ies of the past century and turn out to be a uni versal material for hysteresis motors [ 3 ].
