Electroplastic Effect (EPE) is the influence of electrical current on the microstructure and the plastic flow of materials. In this work, duplex stainless steel UNS S32750 has undergone uniaxial tensile tests with the aid of pulsed electrical current. Different current densities and thermal tests were conducted to separate the EPE from the heating effect. The tested material shows an increase in fracture strain and uniform elongation, while ultimate tensile strength and yield strength were barely affected.

Abstract
Electroplastic Effect (EPE) is the influence of electrical current on the microstructure and the plastic flow of materials. In this work, duplex stainless steel UNS S32750 has undergone uniaxial tensile tests with the aid of pulsed electrical current. Different current densities and thermal tests were conducted to separate the EPE from the heating effect. The tested material shows an increase in fracture strain and uniform elongation, while ultimate tensile strength and yield strength were barely affected.File in questo prodotto:
