“…Magnetic field effect on physical and mechanical properties of nonmagnetic materials was studied in many papers (see, for example [1][2][3][4]). The main part of them is devoted to the investigation of materials (LiF, KCl, KBr, CsI, InSb, Al, Zn, Si, NaNO 2 , ZnS, C 60 , polymers, ect.)…”

The constant magnetic field effect (B≤0.6 T) on creep of polycrystalline copper and its dislocation substructure has been established. The correlation of creep rate to time up to failure has been determined. The magnetic field effect on change of dislocation substructure parameters depending on the distance to the surface of failure (at a distance of 2, 4, 7, 10 and 20 mm from the surface of failure) under creep has been studied. It has been shown that magnetic field affects greatly the redistribution of dislocation substructure types and their scalar density of dislocations. The magnetic field effect on polycrystalline copper is connected with magneto-induction relaxation of dislocation structure.

“…creep) and their operating characteristics should meet special requirements. However, an aggregate and simultaneous action of external energy effects and mechanical loads can greatly reduce the operation life of important devices and structures, which will result in their premature failure [1][2][3][4][5][6]. Hence, studies aimed at extending metal and alloy durability and improving metal part quality are needed.…”

An impact of a weak magnetic field on changes in the dislocation substructure of commercially pure copper exposed to stressing up to destruction under creep conditions was investigated. It was established that a magnetic field action on a metal exposed to creep resulted in the formation of a band dislocation substructure. In some cases grains with the dislocation chaos structure or cellular and grid substructures were revealed. In addition, quantitative differences in the dislocation substructure characteristics were also identified. A gradient nature of changes in the number of stress concentrators when moving away from the failure surface was defined. It was shown that the density of bend extinction contours characterizing the number of stress concentrators in the material decreased when moving away from the failure surface.
