Abstract

Using the powder-metallurgy nickel-based superalloy VZh178P as a prototype the chemical composition of an experimental gas turbine disk alloy with zero γ/γ'-misfit and high phase stability was calculated by the method of computer design. After equiaxed solidification and heat treatment the microstructure of alloy represents a γ-phase strengthened by spherical particles of the γ'-phase with a size of ~0,2 μm. After creep tests (750 °C, σ = 650 MPa, τ = 99 h and 850 °C, σ = 300 MPa, τ = 705 h), the microstructure studies and analysis of the creep mechanisms of the alloy were carried out. No traces of the formation of TPU phases were found in the alloy.
