Description

The passage of slip and the transgranular fracture across the interface of α-β brass two-phase bicrystals were investigated in connection with the orientation relationships of the bicrystals. The passage of slip across the interface was observed in the slip systems with misorientation less than 10 degrees. These results were related to the interface dislocation created when a dislocation propagates across the interface. The twist disclination model proposed by Marcinkowski for the passage of a dislocation across the twist boundary was recognized at the interface of the present two-phase bicrystals. The initiation and the propagation of the transgranular crack was seen at the interface where the passage of slip was investigated. It was noted that this transgranular crack was caused by the high stress field around the deformation ledge created when many dislocations passed through the interface.
