High-temperature alloy grade KHN80TBJU (ЭИ607) Nickel-based ideal for the production of turbines that operated at t° 700 °C. In modern engines the material for turbine blades must possess high resistance to fracture at low-cycle and thermal fatigue, which is now 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. Material requirements for turbine blades due to the latest developments of engine design, they are associated with an increase in plasticity, heat resistance, resistance to dynamic loads and thermal fatigue, and resistance to the effects of gas media.
