摘要：

The tendencies of advancement of refractory nickel alloys with polycrystalline equiaxed structure for casting turbine blades of aircraft engines are considered. Results of design and experimental studies of a new polycrystalline refractory nickel rhenium-containing alloy VZhL22 with equiaxed crystallization are presented. It is shown that alloy VZhL22 possesses high phase stability and enhanced strength , ductility, (delta(20A degrees C) = 8%) and high-temperature strength-to-weight ratio cm(3)).
