Making Strong Alloys Ductile and Hydrogen-Tolerant via Tuning Nanogradients (ARC Discovery Project administered by The University of Sydney) (2023–2026)

Abstract:

This project aims to develop a novel design concept of gradient segregation engineering (GSE) to produce high performance alloys. The innovative GSE will synergistically introduce a chemical gradient via grain boundary segregation and a physical gradient by microstructure control to simultaneously achieve an excellent strength ductility combination and exceptional resistance to hydrogen embrittlement. This project expects to create new fundamental knowledge and provide critical perspectives for future mechanistic alloy design. The results will enhance Australia's capacity to develop next-generation advanced alloys to underpin current and emerging industrial applications and strengthen the country's leading position in materials engineering.
