Metallic materials with combined chemical and structural heterogeneities. This project aims to explore how combined spatial gradients in composition and microstructure affect the mechanical properties of metallic materials.

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.Read moreRead less
