Abstract

A wrought heat-resistant superalloy VZh179-ID has been developed for blades of the last stages of a high-pressure compressor with an operating temperature up to 800 °С of high-thrust gas turbine engines. To achieve the required indicators for mechanical properties structural studies have been carried out, the results of which are used in determining the models of alloy’s heat treatment. According to the complex of mechanical properties the developed alloy has significant quotes of superiority both in comparison with EP718-ID alloy and the most heat-resistant wrought alloy for blades EP220.
