This project is designed to provide a physical metallurgy platform for understanding and interpreting the role of clusters of micro-alloying elements in precipitation in light alloys and aiding new alloy development. Phase transformations play an important role in determining the mechanical properties of many engineering materials. Understanding the origin and impact of solute clustering in phase transformations is crucial for achieving unprecedented properties in these materials. This project plans to combine atomic-scale characterisation and multi-scale computation to reveal the geometry and energetics of solute clusters and cluster-assisted nucleation in light alloys based on aluminium and magnesium. Applications may include the development of stronger and less costly metallic materials for the aerospace, aircraft and automotive industries.

该项目旨在提供一个物理冶金平台，用于理解和解释微合金元素簇在轻合金沉淀中的作用，并帮助新合金的开发。相变在决定许多工程材料的机械性能方面发挥着重要作用。了解相变中溶质聚集的起源和影响对于在这些材料中实现前所未有的性能至关重要。该项目计划将原子尺度表征和多尺度计算结合起来，揭示铝和镁轻合金中溶质团簇的几何形状和能量学以及团簇辅助成核。应用可能包括为航空航天、飞机和汽车工业开发更坚固且成本更低的金属材料。
