摘要
FIELD: nonferrous metallurgy. SUBSTANCE: method involves heating at the rate of 1.5-10 C/s to a temperature 10-30 C lower than the temperature of martensitic transformation tm.t, cooling at the rate of 0.2-1 C/s to a temperature 270-320 C lower than tm.t, repeating the cycle 8-14 times. EFFECT: method ensures a 25-30-% increase of strength and cracking resistance characteristics.
