文摘

The object of the study is polycrystalline copper of M006 brand. The dislocation substructure (DSS), which is formed in copper under the destruction in creep conditions in a magnetic field of 0.35 T, was studied by diffraction electron microscopy. The substructure of the initial state of copper is characterized by the presence of the following DSS types: chaotically distributed dislocations (56%), a cellular substructure of various degrees of perfection (36%), a netlike substructure (5%), a band substructure (3%), dislocation bundles (3%), and broken subboundaries (2%). It is established that the peculiarities in the quantitative ratio of DSS types manifest themselves under destruction in the magnetic field. Notably, the main DSS type near the destruction zone in copper deformed under creep conditions is the subgrain structure. The application of the magnetic field leads to a decrease in the relative content of the subgrain structure in copper by almost a factor of 2. It is shown that the magnetic-field effect retards the transformation rate of the dislocation substructure under creep of copper, which leads to an increase in strength characteristics.
