Abstract:
|
The electroplastic effects on wire drawing process assisted with different short
time current pulses configurations are investigated experimentally. The current
pulses were induced to a specimen during the drawing process. The studied
material is the 308L stainless steel. Current densities of 185 A/mm2, frequencies
range from 140 to 350 Hz and pulse duration range from 100 to 250 μs were
used in the electrically‐assisted wire drawing process. Frequency and pulse
duration are combined to determine which electrical configuration improves the
mechanical behaviour under the electroplasticity phenomenon. The result of the
present study shows a decrease of the drawing forces during wire drawing
processes assisted under different electropulsing configurations. Moreover, a
formability enhancement was noted due to an alteration of the mechanical
behaviour caused by the electropulsing effect |
