Abstract

The fracture behavior of Cu – 0.1% Sn alloy in samples of two types, namely with similar characteristics of ultra-fine-grained structure, but different in the second phase particle size has been investigated. These two types of samples were obtained by means of equal channel angular pressing with different number of passes. It has been found that with increase in the total strain the morphology and orientation of the fracture surface demonstrate changes corresponding to the development of shear mode. The arguments for the hypothesis that the fracture behavior change is connected with the decrease of the particle size and increase of their distribution density are given.
