| Abstract Scope |
In this study, a novel processing technique was proposed for 2014 aluminum alloys to induce effective electro-annealing phenomena. The electro-treatment of the 2014 aluminum alloy induced a micro-hardness reduction with a maximum 48.7% decrement at 2.0 × 10^4 A/cm^2 for 1 h. The softening of the material was proposed to be attributed to the competition between the recrystallization and grain growth (the electro-annealing phenomena) and the precipitate evolution (the electro-dissolution and electro-reprecipitation phenomena), as evidenced by the electron backscatter diffraction (EBSD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD) analyses. The thermal benchmark was also conducted to investigate the synergistic thermal Joule heating effect and athermal electron wind force effect during the electro-treatment. The electrical annealing treatment could be a potential processing technique considering the effective recrystallization and grain growth achievement with the aid of the additional athermal electron wind force effects. |
