Effects of Impulse Current on Mechanical Behavior of Ti and Ta

Abstract:

In this paper, pure metals Ti and Ta were used to study the effects of impulse current on their mechanical properties. The results showed that the impulse current caused the tensile strength of the two metals to decline remarkably. The elongation of metal Ta rose and was enhanced with increasing current density. But as for metal Ti, the elongation hardly rose. Theoretical analysis suggested that the impulse current had little apparent effect on HCP metals, for it had less slip systems; however, it had obvious effects on the elongation of BCC metals, for they had more potential slip systems. The transmission electron microscopy (TEM) observations showed that crystal microstructure of the two metals had not changed significantly.
