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