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 σ0.2 are preserved owing to increased limiting relative elongation δ value.
EFFECT: raised brittle fracture threshold.
