EFFECT OF DIFFERENT SCHEMES OF COMBINED PLASTIC DEFORMATION ON PHYSICAL AND MECHANICAL PROPERTIES OF COPPER М0б
Physical and mechanical properties of copper М0б are studied after deformation by different schemes of combined processing including equal-channel angular pressing (ECAP) and one of the methods of conventional treatment (upsetting, rolling, drawing). It is shown that the application of combined treatment allows obtaining of a higher set of physical and mechanical properties of the material as compared to the conventional technologies. The effect of defect formation on the mechanical and physical properties of the material is established that is added in the course of deformation treatment (pores and microcracks).
