  • Publication number: 20220017998
    Abstract: The method of producing composite material with a high complex of mechanical properties, consisting of vanadium alloy inner layer V—3-11 wt % Ti—3-6 wt % Cr and two outer layers of stainless steel of ferritic grade with chromium content of not less than 13 wt %, includes preparation of a composite workpiece consisting of said inner layer and outer layers, hot treatment by pressure and subsequent exposure in furnace. Prepared composite workpiece, thickness of inner layer of which is 1.5-2 times more than total thickness of outer layers of stainless steel, hot working is performed with pressure of the workpiece in the temperature range of 1,050-1,150° C. with degree of reduction from 30 to 40% and with subsequent exposure for 1-3 hours with temperature reduction to 500-700° C., then annealing workpiece by heating to temperature of 850-950° C., holding for 2-4 hours and subsequent cooling in furnace.
