Abstract
The tensile properties and bending behavior of Ti6Al4V alloy sheet with pulse current were studied. The current density greatly affects the tensile strength and elongation. With current density increasing, the flow stress greatly reduces and the elongation obviously increases. Actually, the effect of the pulse current on flow stress is more significant than that on the failure strain. The current pulse can obviously improve the bending properties of Ti6Al4V alloy. The bending cracks can be avoided with current pulse, which always appears with no current. The electroplastic effect mainly results from a comprehensive function of Joule heating and pure electroplastic effect. Among them, Joule heating effect perhaps plays a dominant factor.
