Formation of interphase nanoparticles and clusters is a new approach to increase strength in advanced high strength steels. Exceptionally high strength levels can be achieved in alloys that only have solute clusters by controlling the temperature-time history. However, the exact mechanism for the formation of clusters and precipitates and the cluster strengthening mechanism are not understood, nor do we know how to control cluster formation. This project aims to develop a fundamental understanding of the formation of clusters and nanoprecipitates and determine their contribution to strengthening and other mechanical properties using advanced characterisation techniques such as atom probe tomography and electron microscopy.

界面纳米颗粒和团簇的形成是提高先进高强度钢强度的新途径。通过控制温度-时间历程，可以在仅具有溶质团簇的合金中实现异常高的强度水平。然而，形成团簇和沉淀物的确切机制以及团簇强化机制尚不清楚，也不知道如何控制团簇的形成。该项目的目的是发展形成的集群和纳米沉淀物的基本理解，并确定其使用先进的表征技术，如原子探针断层扫描和电子显微镜的强化和其他机械性能的贡献。
