摘要	Cu bicrystals with a twin boundary (TB) and all {111} grain boundary (GB) were cyclically deformed. It is shown that the slip bands in the two component grains of both bicrystals are parallel to the TB and GB, respectively. Despite no piling up of dislocations, fatigue cracks still nucleate preferentially along the TB and GB in a shearing mode. The experimental results demonstrate that the inclined interfaces of {11 1) plane usually show low resistance to the shear fatigue cracking. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd.
