ELECTROPLASTIC EFFECT IN NANOSTRUCTURED TITANIUM ALLOYS

Features of the influence of plastic deformation in the presence of electrical current on the structure and mechanical properties of titanium alloys VT1-0, VT6, and Ti 49.3 Ni 50.7 in coarse- grained (CG) and ultrafine-grained (UFG) states were investigated. Introduction of a pulse cur- rent during cold rolling leads to the increase in deformability, and during tension loading it causes occurrence of stress jumps connected with phase transformation or electroplastic effect (EPE). It is shown that EPE is the structurally-sensitive property dependent on the grain size.
