The purpose of the work consists in the investigation of stress-strain properties and destruction mechanism of low-alloy steel 09G2S subjected to extrusion and uniformly channel angular pressing (UCAP). The combined method of
Strain processing consists in the successive use of extrusion methods and UCAP. There is shown an example of low-alloy steel 09G2S strengthening with the use of extrusion and UCAP. There are presented data on stress-strain properties and destruction mechanism of steel 09G2S samples at uniaxial tension at the state of delivery and after strengthening. Strength increase and steel plasticity decrease is shown. On the basis of the results of fractal graphics analysis a viscous character of steel 09G2S destruction at the state of delivery and after extrusion and UCAP is defined.
