One of the main impediments to increased use of wrought magnesium is its characteristic but mediocre mechanical properties. The proposed work paves the way for new improved wrought magnesium alloys by determining how the constituent nano-structures, micro-structures and deformation conditions can be manipulated to control the evolution of properties during annealing. The project will deliver mathematical models describing the annealed microstructure and mechanical properties. The work will also explore the potential of a recent discovery made by the CI of a simple technique to randomise the alignment of the annealed atomic lattice structure, which promises to markedly improve formability.

增加锻镁使用的主要障碍之一是其独特但机械性能平庸。这项工作通过确定如何操纵纳米结构、微观结构和变形条件来控制退火过程中性能的演变，为新型改进的变形镁合金铺平了道路。该项目将提供描述退火微观结构和机械性能的数学模型。这项工作还将探索 CI 最近发现的一种简单技术的潜力，该技术可以随机化退火原子晶格结构的排列，这有望显着提高可成形性。
