Short-term thermal cyclic creep and fracture of a VT1-0 titanium alloy in a hydrogen atmosphere

Abstract

The short term creep and fracture of a VT1 0 titanium alloy are studied under conditions of con stant tensile stresses during cyclic heating to temperatures of 600-1100°C in a hydrogen atmosphere at a pressure of 0.5 MPa. The dependences of the low cycle thermal cyclic fatigue diagram and the creep rate on the heating temperature and the tensile stresses are presented.
