The main goal of this comprehensive research project is to advance our current mechanistic understanding of the deformation and dynamic recrystallization phenomena in magnesium and its alloys. The research proposed is to be conducted on oriented magnesium and magnesium alloy (Mg-1Gd and Mg-4Li) single crystals tested in different loading orientations via plane strain compression at various temperatures. The interplay between the activated deformation mechanisms, dynamic recrystallization, and texture and microstructure evolution is systematically investigated utilizing sophisticated X-ray diffraction and electron microscopy techniques. The deliverables of this project will help us to understand and predict the deformation and fracture behavior of hcp metals, and design appropriate components and forming processes.

这一综合性研究项目的主要目的是提高我们目前对镁及镁合金变形和动态再结晶现象的机理认识。本研究拟对取向镁及镁合金(镁-1Gd和镁-4Li)单晶在不同加载方向下进行不同温度下的平面应变压缩试验。利用先进的X射线衍射和电子显微镜技术，系统地研究了激活变形机制、动态再结晶以及织构和组织演变之间的相互作用。该项目的成果将帮助我们了解和预测HCP金属的变形和断裂行为，并设计合适的成分和成形工艺。
