The rebound suppression and rapid solid solution of Al–Zn–Mg–Cu alloy under high-density electropulsing

Journal of Materials Research and Technology
As a high-strength aluminum alloy, Al–Zn–Mg–Cu alloy is widely used in aerospace and aviation applications. Due to the high yield strength and low modulus of elasticity, Al–Zn–Mg–Cu alloy is prone to springback problems during processing, which limits ...

Critical Assessment 8: Outstanding issues in electropulsing processing

, 2014
The processing of materials using electrical pulses utilises effects other than resistive heating to stimulate changes in their microstructure and hence the properties. The direct effect of electropulsing has not, however, been fully understood.
