Making Strong Alloys Ductile and Hydrogen-Tolerant via Tuning Nanogradients

本计画旨在发展一种新的梯度偏析工程设计概念，以生产高性能合金。创新的GSE将通过晶界偏析协同引入化学梯度，并通过微观结构控制引入物理梯度，以同时实现优异的强度-延展性组合和优异的抗氢脆性。该项目期望创造新的基础知识，并为未来的机械合金设计提供关键的观点。研究结果将提高澳大利亚开发下一代先进合金的能力，以支持当前和新兴的工业应用，并加强该国在材料工程领域的领先地位。

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.
