Thermal fatigue resistance of a monocrystalline alloy

Specific features of thermal fatigue fracture of a monocrystalline alloy used in manufacturing of rotor blades of gas-turbine units are investigated. The dependences of the number of cycles to failure on the crystallographic orientation of the material, maximum temperature in a cycle, temperature ra...

Summary:Specific features of thermal fatigue fracture of a monocrystalline alloy used in manufacturing of rotor blades of gas-turbine units are investigated. The dependences of the number of cycles to failure on the crystallographic orientation of the material, maximum temperature in a cycle, temperature range, and stress concentration are established. The effects of the pores and processes of recrystallization on the degree of thermal fatigue damage are analyzed.
