摘要

利用 Cr、Mo、Nb、V、Cu 和其他元素对钢材性能影响的协同效应，开发出了一种具有高性能的低合金结构钢。对该钢的微观结构、机械性能和耐腐蚀性能进行了研究。钢的结构是多相的，由多边形铁素体和 M/A 岛组成。钢在 600°C 时的屈服强度至少是室温下屈服强度的 2/3。在盐雾腐蚀作用的 360 小时内，钢的腐蚀速率随时间的增加而逐渐降低，锈层结构由疏松变为致密。钢材的机械性能、耐热性、耐腐蚀性和耐热性符合建筑结构材料的要求。

Microstructure and Operational Properties of Low-Alloy Low-Carbon Steel for Building Structures

Using the synergistic effect of the influence of Cr, Mo, Nb, V, Cu, and other elements on the properties of steels, a low-alloy structural steel with high performance properties has been developed. The microstructure, mechanical properties and corrosion resistance of the steel have been studied. The steel structure is multiphase and consists of polygonal ferrite and M/A islands. The yield strength of the steel at 600°C is at least 2/3 of the yield strength at room temperature. During 360 h of the corrosive effect of salt mist, the corrosion rate of the steel gradually decreases with increase of the time, and the structure of the rust layer is transformed from loose to dense. The mechanical properties, heat resistance, corrosion resistance and heat resistance of steel meet the requirements for materials of building structures.
