DUCTILE FRACTURE IN COPPER SINGLE CRYSTALS.

Abstract

Metallographic and x-ray studies in the vicinity of the necks of fractured copper single crystals oriented for multiple slip have shown that initial necking takes place by general deformation followed by localized shearing after a well-developed neck has formed. Lattice rotation was observed to occur in the necked region during general deformation; void growth and quadrangular cavity formation, during localized shear process.
