Abstract

The work is devoted to the study of heat resistance and technological plasticity of a new heat-resistant alloy of the Fe–Cr–Al–Y system. The alloy of the Fe–Cr–Al–Y system being developed 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 at 1100 °С, the alloy of the Fe–Cr–Al–Y system is 1.5–2 times superior to alloys analogs ЭИ435 and ЭИ868.
