Zusammenfassung:FIELD: iron-based alloys. ^ SUBSTANCE: invention relates to dispersionally-hardening alloys based on W-alloyed Fe-Cr-Co. Iron-based alloy containing 21-23% chromium, 14-16% cobalt, 14-16% tungsten, and 0.5-3% gallium has optimal magnetic and mechanical properties allowing the alloy to be used for manufacturing rotors of high-speed hysteresis engines exhibiting high power and efficiency. Required HC and sigma0.2 are preserved owing to increased limiting relative elongation delta value. ^ EFFECT: raised brittle fracture threshold. ^ 2 tbl
