摘要

This study systematically examines the influence of texture on the mechanical behavior of a hot-rolled Mg–2Zn–0.1Ca alloy. When subjected to tensile loading along the rolling direction (RD), the alloy exhibits superior strength and ductility compared with loading along the transverse direction (TD). Slip-trace analysis reveals that the deformation mode in the TD specimens is predominantly governed by basal slip, whereas the RD specimens show pronounced activation of non-basal slip systems. A modified Hall–Petch relationship, incorporating the combined effects of texture and grain size, suggests that the synergistic contribution of finer grains and a texture that reduces the average Schmid factor for basal slip is closely associated with strength enhancement. Furthermore, the increased work-hardening capacity and improved deformation compatibility promote a more homogeneous strain distribution, thereby delaying intergranular crack initiation and ultimately leading to enhanced ductility.
