Abstract

Results of design and experimental studies of a nickel-based superalloy VZhL20 with a density of 8.04 g/cm3 for the manufacture of turbine blades with a columnar granular structure and a single-crystal structure are presented. It is shown that alloy VZHL20 with a single-crystal structure of the crystallographic orientation [001] in the heat-treated state possesses high phase stability, and enhanced short-term strength (\( \sigma_{0,2}^{20} = 950 \, \text{МПа} \) и \( \sigma_{\delta}^{20} = 1130 \, \text{МПа} \)) and long-term strength (\( \sigma_{100}^{900} = 340 \, \text{МПа} \) и \( \sigma_{100}^{1000} = 185 \, \text{МПа} \))
