Abstract

Electricity-assisted metal forming, especially using pulsed-current, was demonstrated to promote a drop in flow stress and improving formability. To investigate the effect of pulsed-current on stress relaxation, a uniaxial tensile test was conducted with different pulsed-current parameters by changing its pulse-width and frequency. Short pulse-width was used in the range of microseconds, while the frequency was arranged under 1 kHz. Different level of temperature was used to consider the effect from joule heating. Stress relaxation in the tensile test was repeated at constant strain interval at 3% strain. This research presents an analysis of stress relaxation influenced by the time-dependent parameter of short pulsed-current.
