Abstract : The effects of crystallographic orientation, temperature and stacking fault energy on the rate of fatigue crack propagation have been studied in polycrystalline copper, copper single crystals and copper-aluminum single crystals at room temperature and at liquid nitrogen temperature. The results were discussed in terms of cyclic hardening and the case of dislocation cross slip. (Author)
