Stage I cracking along two or more {111} planes can occur from the notch root simultaneously. There exists an orientation dependence of the crack initiation threshold under cyclic compression. The cleavage chunk falling off from the specimen surface due to the intersection of different {111} planes was observed in (100)[010] specimen, but never observed in (110)[110] specimen. Subsequently, the mechanism of crack growth which is dependent on orientation was proposed in this paper.
