ELECTROPLASTIC EFFECT IN NANOSTRUCTURED
TITANIUM ALLOYS

Vladimir Vladimirovich Stolyarov

Abstract

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 49.3Ni 50.7 in coarsegrained (CG) and ultrafine-grained (UFG) states were investigated. Introduction of a pulse current 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.
