Implication

Quasi in-situ EBSD analysis reveals grain rotation and selective boundary migration in extruded Mg-Zn-Gd alloy, indicating that boundary energy minimization drives non-basal texture formation.

Key Points

Investigate grain boundary characteristics, grain rotation, and texture development in an extruded magnesium-zinc-gadolinium alloy during isothermal annealing.
Subjected extruded Mg-Zn-Gd alloy samples to isothermal annealing at 400 °C for durations between 5 and 155 minutes.
Used quasi in-situ electron backscatter diffraction (EBSD) to track grain growth kinetics, basal pole rotations, and coincidence site lattice (CSL) boundary evolution.
Grain growth occurred through triple junction nucleation and Burke–Turnbull-governed boundary migration, accompanied by (0001) basal pole rotations between 31° and 40° that yielded a non-basal texture.
High-misfit-strain CSL boundaries (Σ7, Σ13b, and Σ45a) decreased in length fraction during annealing, while energetically favored boundaries (Σ9, Σ21a, and Σ43b) increased.
