High pulsed current density has both thermal and athermal effects on the metals, meaning that it can be used to promote the metal forming efficiency. Additionally, it can also be used in the creep-ageing forming of high-strength aluminum alloys. In this present study, the creep-aging behavior, mechanical properties, and microstructural evolution were investigated at various current densities of AA7150 aluminum alloy. The results have shown that the electropulsing treatment (EPT) can increase the dislocation movement and decrease the dislocation density for the coupling of thermal and athermal ...
