The refractory complex alloys based on nickel grade HN55MBYU (HN63M9B2YU; EP666; HN55MBYU-VD; HN55MBYU-ID; EP666-VD; EP666-ID) is used for power engineering components of gas turbine engines, valves of nuclear power plants. In modern engines material for turbine blades must have high resistance to fracture at low-cycle fatigue and heat, which is today the main cause of the destruction. The danger may be aggravated by the destruction of surface reactions that are associated with the softening of grain boundaries, corrosion gas. the material requirements for turbine blades due to the latest developments of engine design, they aim to increase the ductility, heat resistance, resistance to dynamic loads and to thermal fatigue, and resistance to gas corrosion.
Flat and long semi-finished products: bars, rods, hot-rolled sheets, forgings, tubing. The maximum recommended operating temperature for a limited time is 900 ° C, while t ° environment in which starts an intense scaling = 1100 ° C.
