| Abstract Scope |
Using the calculation and analytical methods for forecasting phase and structural stability it is developed the heat-resistant nickel alloy which 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 ºC, as well as time to failure at a test temperature of 975 ºC 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. |
