文摘
In this article, we report the effect of electric field (EF) on the precipitation behavior of Al-Cu-Mg alloy. It is found that the applied field increases the hardness of Al-Cu-Mg alloy at initial aging stage. The peak of the S phase formation determined by differential scanning calorimetry also shifts to lower temperature with the applied EF. These are attributed to a lower decreasing rate of density of vacancies under field which is verified by positron annihilation measurements. The built-in field caused by the rearrangement of vacancy-solute atom complexes might lower the barrier for vacancy to escape from a complex. It leads to a longer survival time of vacancies, resulting in more possible nucleation sites for clusters.
