FIELD: metallurgy.
SUBSTANCE: invention relates to deformed precipitation hardening alloy on the basis of nickel-chrome-cobalt for components of gas turbines. Alloy contains, in wt %: from 17 up to 22 of chrome, from 8 up to 15 of cobalt, from 4.0 up to 9.5 of molybdenum, from 7 of tungsten, from 1.28 up to 1.65 of aluminium, from 1.50 up to 2.30 of titanium, from 0.80 of niobium, from 0.01 up to 0.2 of carbon, from 0.01 of boron, nickel and admixtures-the rest.
EFFECT: alloy allows high cracking resistance under action of tensions as a result of aging, high heat resistance and high creep resistance.
