摘要

本研究研究了热挤压Zn-0.5Mn-0.2 Mg合金在300°C 1 min、300°C 20 min和380°C 24 h三种热处理下的退火行为和织构演变。短期退火通过恢复和亚晶形成促进织构演变，而长时间退火则导致晶粒长大和织构强化。不同于预期的高织构纤维的纤维成分的发展是织构演变的特征。重合点格（CSL）边界的出现，包括39°<；0-110>；72°<0-110°>；进一步强调了晶界（GB）特性对Zn微观组织稳定的重要性。

Development of annealing texture in biodegradable Zn-Mn-Mg alloy

This study examines the annealing behavior and texture evolution of a hot-extruded Zn-0.5Mn-0.2 Mg alloy under three thermal treatments: 300 °C for 1 min, 300 °C for 20 min, and 380 °C for 24 h. Short-term annealing promotes texture evolution through recovery and subgrain formation, whereas prolonged exposure leads to grain growth and texture strengthening. The development of a fibre component different from expected high-texture ones characterizes texture evolution. The emergence of coincidence site lattice (CSL) boundaries, including 39° <0-110> and 72° <0-110> misorientations, further underscores the importance of grain boundary (GB) character on Zn microstructure stabilization.
