摘要

Fatigue tests are performed on the Cu-2.16Ni-0.72Si alloy, at different stress ratios, R. at room temperature and 473 K. For R = 0.4 the fatigue strength decreases when temperature is increased. The observation of intergranular cracking on fracture surfaces shows that this phenomenon is related to dynamic embrittlement.
