Abstract
Previous studies have established that the presence of an electric current within a metal during deformation can provide the same altered mechanical properties as working the specimen at an elevated temperature, while avoiding the negative effects associated with hot working. These previous studies indicated that the electrical current could significantly improve the formability of Aluminum alloys without appreciably raising the temperature. Considering this, the research herein further investigates this potential by examining the effect of pulsed direct current on the formability of 5754 Aluminum sheet metal, an alloy of interest within the automotive industry. The results show, with the proper parameters, a pulsed electrical current, applied during continuous tensile deformation, significantly improves the maximum elongation of the Aluminum. Moreover, in contrast to hot working, pulsing the electricity during deformation did not alter the Aluminum's grain structure/size and had very little effect on the number of microvoids within the Aluminum.
