DEFORMED HIGH-ENTROPY ALLOY FOR HIGH-TEMPERATURE APPLICATIONS Russian patent published in 2019 - IPC C22C14/00 C22C30/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, particularly to deformable high-entropy alloys, and can be used for production of structures operating under high temperatures in gas turbine engines. High-entropy Ti_aNb_bCr_cV_d deformable alloy has following ratio of components, atm. %: titanium (a) – 42.7, niobium (b) – 23.0, chromium (c) – 22.1, vanadium (d) – 12.2. Alloy has high specific yield point of more than 150 kPa·m³/kg at T = 700 °C, density of less than 6.5 g/cm³, and also has high plasticity of not less than 50 % at room temperature and capacity for deformation treatment by cold rolling.

EFFECT: deformed high-entropy alloy is proposed for high-temperature applications.
