In this work, to study the effects of stress triaxiality, temperature, and strain rate on the fracture behaviors of a single-crystal Nickel-base superalloy, a series of experiments over a temperature range of 293 to 1373 K, strain rate range of 0.001 to 4000/s, and stress triaxiality range of −0.6 to 1.1 are conducted. Anomalous peak of stress is noticed in the yield stress versus temperature curves,...
