P2-17: Development of Rhenium Free Heat-resistant Nickel Alloy for the Cast Blades Production by the Method of Directional Crystallization: Evgeniy Milonin¹; Konstantin Balushok¹; Pavel Malinovskiy¹; Valeriy Naumyk²; Vadim Shalomeev²; Sergey Sheyko³; ¹JSC «Motor Sich»; ²NU "Zaporizhzhya Polytechnic"; ³Zaporizhzhia National University
    Based on the use of calculation and analytical methods for forecasting phase and structural stability, the heat-resistant nickel alloy ЗМИ-M5 chemical composition has been developed. This alloy does not contain rhenium, contains an increased amount of tantalum and tungsten (8.5% at the average level) and intended for manufacturing of cast working blades by the method of directional crystallization. Developed alloy after heat treatment, under the regime foreseen for modern IV generation alloys provides a tensile strength above 1300 MPa with satisfactory ductility (more than 6.0%) at a temperature of 20 șC, as well as time to failure at a test temperature of 975 șC and a load of 300 MPa 60...90 hours, which meets the requirements for the serial alloy ЖС32-ВИ and it is much less expensive.
