Abstract

The tensile experiments were carried out under different conditions of pulse current on pure titanium. The influence of pulse current density on the the actual stress strain curve, elongation and the tensile strength were also analyzed. The experimental results show that pulse current could change material elastic constants and result in a decline in the yield stress of the material. With the pulse current, the tensile strength of Ti decreased by 62.2% while its elongation kept almost unchanged. At the same time, microstructure was also different. With the increase of pulse current density, grain size of Ti tends to be more uniform and equiaxial and a directional arrangement of the grain can be more easily observed.. It showed that intracrystalline defects were decreased gradually with the low quantity of slip system and dislocation, for the electronic wind caused by drift electrons was not strong enough for the dislocation motion.
