Abstract

The fractography of copper destroyed under creep conditions in a magnetic field of 0.35 T is studied by scanning electron microscopy. The qualitative similarity of the fracture surface morphology, formed in the presence of a magnetic field and without it is revealed. It is shown that in the presence of a magnetic field the average sizes of the formed surface relief in a fiber fracture zone are smaller, and in the radial zone they are larger than that in the corresponding zones of the material deformed under normal experimental conditions. It is revealed that exposure to a magnetic field during the creep deformation mode leads to expansion of the pit size range in the fiber area and to its narrowing in the radial zone. It is found that the application of a magnetic field affects the rate of accumulation and annihilation mechanisms of initiation and defect restructuring of the volume and near-surface layer of copper samples.
