Fracture topography of commercial copper

There is an interest in relating the fracture process of metallic materials to the plastic deformation mechanisms which precede fracture. Thus, in many reported cases the fracturing path follows the dislocation cell walls present in the material and hence can be directly correlated to the dislocation cell structures. This study examines this hypothesis for high purity (99.94%) commercial copper containing inclusions. Tensile specimens, having …
