High-temperature alloy grade KHN62MVKJU (KHN62MVKJU-VD, ЭИ867-VD, ЭИ867) intended for the manufacture of turbine blades that operate at temperatures above 900 °C. In modern engines the material for parts of turbines should have a high resistance to fracture at low-cycle and thermal fatigue, which is today the main cause of the destruction. The danger of destruction may be exacerbated by surface reactions, which are associated with weakening of grain boundaries, gas corrosion. The main material requirements for turbine blades is caused by the latest developments of engine design, high ductility, heat resistance, resistance to low cycle and thermal fatigue, and resistance to gas environments.
