This paper investigated the intermediate temperature embrittlement phenomenon in the electrical-assisted tensile test of copper. Both the reduction of area and elongation decreased significantly in electrical-assisted tension. Many cavities were found on the surface of fractured sample, and most of the cavities are located near the grain boundary and a few of them are in the grain interior. Based on experimental and computational results, it is concluded that the fracture behavior is mainly ruled by the aggregation and coalescence of cavities that is possibly induced by trace concentration of sulfur solutes.
