摘要：

The article deals with the problems of strengthening and cold resistance increase of steels through combining equal channel angular pressing (ECAP) with thermal processing (TP). Dependence of cold resistance on the state of the material structure determined by regimes of equal channel angular pressing and thermal processing is shown. Dependence of specific work of plastic deformations, stored and dissipated energy of steel on its plasticity is stated.
