- Abstract
Precipitation on deformation defects is essential for enhancing mechanical properties of age-hardenable alloys. In this work, we revealed how {10-12} twin boundary (TB) influences β-Mg17Al12 precipitation in Mg-9Al-1Zn alloy. The precipitates on the TBs are rodlike, while others are lath shape. Most precipitates hold the Burgers orientation relationship (OR) only with twin or matrix. Moreover, certain precipitate variants are absent and a new rule for variant selection on TB is proposed.
