Abstract

The work is devoted to the development of a technology for producing a cold-rolled sheet from a heat-resistant alloy of the Fe–Cr–Al–Y system. The alloy of the Fe–Cr–Al–Y is intended for the manufacture of honeycomb seals for the flow path of gas turbine engines with an operating temperature of up to 1100 °С. This alloy is intended to replace heat-resistant alloys ЭИ435 and ЭИ868, which are currently used for the manufacture of honeycomb seals. In terms of heat resistance, the alloy of the Fe–Cr–Al–Y system is significantly superior to nickel alloys ЭИ435 and ЭИ868.
