This project aims to explore how combined spatial gradients in composition and microstructure affect the mechanical properties of metallic materials. Manipulation of composition and microstructure has been widely used to strengthen materials but this often deteriorates the ductility. The trade-off could be overcome through the introduction of gradient structures because the variations in both composition and microstructure would trigger simultaneous activation of multiple deformation mechanisms. This project is expected to provide guidance in the design of gradient metallic structures with optimum mechanical properties, which will significantly benefit Australian metallurgical and related industries.

该项目旨在探索成分和微观结构的组合空间梯度如何影响金属材料的机械性能。成分和微观结构的控制已被广泛用于强化材料，但这通常会降低延展性。这种权衡可以通过引入梯度结构来克服，因为成分和微观结构的变化会触发多种变形机制的同时激活。该项目预计将为具有最佳机械性能的梯度金属结构的设计提供指导，这将使澳大利亚冶金及相关行业受益匪浅。
