Abstract

The mechanical properties of Al–Mg–Si alloys are linked to their thermomechanical process history. The objective of this study is to provide a quantitative assessment of the effect of quench rate after solution treatment on the strain distribution at the microstructural level using high-resolution digital image correlation (HRDIC). The microstructure was characterized using electron backscattered diffraction (EBSD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). It was found that solute depleted areas formed near grain boundaries are sites for strain localization during deformation.
