Cast AZ31B-H24 magnesium alloy, comprising Mg with 3.27 wt% Al and 0.96 wt% Zn, was cold rolled and subsequently annealed. Global texture evolutions in the specimens were observed by X-ray diffractometry after the thermomechanical processing. Image-based microstructure and texture for the deformed, recrystallized, and grown grains were observed by electron backscattered diffractometry. Recrystallized grains could be distinguished from deformed ones by analyzing grain orientation spread. Split basal texture of ca. ±10-15° in the rolling direction was observed in the cold-rolled sample. Recrystallized grains had widely spread basal poles at nucleation stage; strong {0001} basal texture developed with grain growth during annealing.
铸态 AZ31B-H24 镁合金，其成分为 Mg （3.27wt%Al 和 0.96wt%Zn），经过冷轧和随后的退火处理。通过 X 射线衍射法观察了热机械加工后试样的整体织构演变。通过电子背散射衍射法观察了变形、再结晶和生长晶粒的基于图像的微观结构和织构。通过分析晶粒取向分布，可以将再结晶晶粒与变形晶粒区分开来。在冷轧样品中观察到约 10-15°的分裂基面织构。在形核阶段，再结晶晶粒的基面极点分布较广；在退火过程中，随着晶粒生长，形成了强烈的{0001}基面织构。
