Engineering hierarchical microstructures in high strength low alloy steels

该项目旨在开发一种新的钢铁加工技术，通过多尺度分层微结构同时提高强度和延展性。具体地说，将通过控制析出、偏析和溶质原子聚集来生产超细晶粒钢。原子探针结晶学将用于研究晶界的结构和化学，为结构钢的韧性提供新的见解。预期的结果将是为未来更坚固、更具延展性和更安全的高强度低合金钢确定潜在的新制造路线。

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.
