Abstract

This study systematically explores the impact of annealing temperature on the microstructural evolution and corrosion resistance of low-Cr ferritic stainless steel. The results demonstrated a significant enhancement in corrosion resistance following cold rolling and annealing. Notably, increasing the annealing temperature contributed to a substantial reduce in ferrite grain size from 61.92 μm to 16.23 μm and an increased proportion of martensite from 22.13 % to 48.99 %. Moreover, the sample annealed at 860 °C demonstrated excellent corrosion resistance due to the improved passive film stability, driven by the refinement of ferrite grain size.

通过调整退火温度优化低铬铁素体不锈钢的组织和腐蚀行为

本研究系统地探讨了退火温度对低铬铁素体不锈钢组织演变和耐蚀性的影响。结果表明，经过冷轧和退火处理后，合金的耐腐蚀性能显著提高。当退火温度升高时，铁素体晶粒尺寸从61.92 μm减小到16.23 μm，马氏体比例从22.13%增加到48.99%。此外，在860℃退火后，由于铁素体晶粒尺寸的细化，钝化膜的稳定性得到了改善，因此样品具有优异的耐腐蚀性。

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
