Cluster hardening of metastable steel alloys produced by thin strip casting

该项目的目标是产生足够的知识，将薄带连铸应用于更广泛的钢种，并降低全球钢板生产的能源成本。每年生产超过10亿吨钢。直接薄带连铸是一种新兴的绿色技术，可将液态钢加工成薄板产品所需的能量降低90%。本研究计划使用先进的原子尺度表征技术，如原子探针层析成像和高分辨率电子显微镜，以了解薄带连铸过程中由于极快的冷却速率而产生的非平衡微观结构。

The goal of this project is to generate sufficient knowledge to apply strip casting to a wider range of steel grades and reduce the global energy cost of steel sheet production. Over 1 billion tonnes of steel is produced every year. Direct strip casting is an emerging green technology that reduces the energy required to process liquid steel into thin sheet product by up to 90 per cent. This study plans to use advanced atomic-scale characterisation techniques such as atom probe tomography and high-resolution electron microscopy to understand the non-equilibrium microstructures that develop as a result of the extremely rapid cooling rates experienced during strip casting.
