摘要：
The flight mission of aeroengines exhibits dynamic features during operation. It is crucial to consider the effect of abrupt loading conditions when evaluating the creep behavior of turbine blades. In this paper, the effect of variable temperature and stress on creep rupture behavior of Ni-based single crystal (SX) turbine blade simulator specimen was systematically studied by experimental and finite element analysis methods. The experimental results indicated that creep strain jump could be observed with increasing temperature and stress, accompanied by the new primary and secondary stages. T...
