The paper considers the influence of the temperature regime of severe plastic deformation of constructional steel by equal-channel angular pressing on the character of fracture during Charpy impact tests. It is shown that the formation of a more developed fracture surface with splits, pits and micropores corresponds to a higher value of impact strength, i.e., an increase in the ability to absorb mechanical energy under the impact load of the specimens.
