This project aims to develop a new steel processing technology that will simultaneously increase strength and ductility via multi-scale hierarchical microstructures. Specifically, ultra-fine grain sized steels will be produced with controlled precipitation, segregation and solute atom clustering. Atom probe crystallography will be used to study the structure and chemistry of grain boundaries, providing new insights into the toughness of structural steels. The expected outcome will be the identification of potential new manufacturing routes for future high strength low alloy steels that are stronger, more ductile, and safer.

该项目旨在开发一种新的钢化处理技术，该技术将通过多尺度分层微观结构同时提高强度和延展性。具体而言，将通过受控的沉淀，隔离和溶质原子聚类产生超细谷物尺寸的钢。原子探针晶体学将用于研究晶界的结构和化学，为结构钢的韧性提供了新的见解。预期的结果将是对未来高强度低合金钢的潜在新制造途径的识别，该途径更强大，更易延展和更安全。
