Correlation between crystallographic anisotropy and dendritic orientation selection of binary magnesium alloys

Jinglian Du; Zhipeng Guo; Ang Zhang; Manhong Yang; Mei Li; Shoumei Xiong

Both synchrotron X-ray tomography and EBSD characterization revealed that the preferred growth directions of magnesium alloy dendrite change as the type and amount of solute elements. Such growth behavior was further investigated by evaluating the orientation-dependent surface energy and the subsequent crystallographic anisotropy via ab-initio calculations based on density functional theory and hcp lattice structure. It was found that for most binary magnesium alloys, the preferred growth direction of the α-Mg dendrite in the basal plane is always
