Origin and impact of solute clustering in light alloys

该项目旨在为理解和解释轻合金中微合金元素簇在沉淀中的作用提供一个物理冶金平台，并为新合金的开发提供帮助。相变在决定许多工程材料的力学性能方面起着重要作用。了解溶质团簇在相变中的起源和影响对于在这些材料中获得前所未有的性能至关重要。该项目计划结合原子尺度表征和多尺度计算来揭示基于铝和镁的轻合金中溶质团簇和团簇辅助成核的几何和能量学。应用可能包括为航空航天、飞机和汽车工业开发更坚固、成本更低的金属材料。

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.
