FIELD: metallurgy. SUBSTANCE: alloys are saturated with hydrogen up to concentration of 0.2 - 0.8 mass %, heat up to temperature, that is 110 - 200 C higher, than temperature of polymorphous transformation of containing hydrogen alloy, then holding for 0.25 - 1 hour is exercised, then hardening is carried out by cooling at speed of 1 - 150 C/s. Method provides increase of form reduction degree by 3 - 4.5 times. EFFECT: method provides increase of form reduction degree. 1 tbl
