Enhancement in the strength of austenitic steels with a small content of carbon can be achieved by a limited number of methods, among which is ultrafine-grained (UFG) structure formation. This method is especially efficient with the use of severe pla

The effect of equal-channel angular pressing (ECAP) and subsequent aging on the structure and mechanical properties of Cu–7% Cr and Cu–10% Fe alloys is studied. ECAP is shown to substantially refine the structure of both alloys. The average grain

In this study, a novel severe plastic deformation technique referred to as rotational constrained bending (RCB) is introduced. A special constrained bending die, which imposes bending deformation to the billet during the first pass, was developed for
