摘要:

采用一步贝氏体等温转变、两步贝氏体等温转变和淬火工艺对中碳钢进行热处理，对不同实验钢的显微组织、物相分布、原位腐蚀和电化学性能进行了表征和测试。结果表明，与一步贝氏体等温工艺和淬火工艺相比，两步贝氏体等温转变工艺后形成的超细贝氏体钢中残余奥氏体含量更小，组织更加均匀。在贝氏体铁素体-残余奥氏体形成的微电偶作用下，超细贝氏体钢中贝氏体铁素体相选择性溶解，产生点蚀坑并沿着板条方向扩展，而均匀分布的薄膜状残余奥氏体阻碍了腐蚀的进一步发展。电化学测试结果显示，在0.5% (质量分数) NaCl溶液中两步贝氏体钢的耐腐蚀性能较一步贝氏体钢和马氏体钢更为优异。

Abstract：

A medium carbon steel was heat treated by one-step bainite isothermal, two-step bainite isothermal- and quenching-treatment respectively, and the microstructure, phase distribution, corrosion performance and electrochemical properties of the different heat treated steels were characterized. The results show that compared with the one-step bainite isothermal- and quenching-treated steels, the ultrafine bainite steel after the two-step bainite isothermal treatment has a more uniform structure with smaller proportion of retained austenite. The bainite ferrite phase in the ultrafine bainite steel is selectively dissolved due to the micro-galvanic effect between bainite ferrite and massive retained austenite, resulting in the initiation and propagation of pitting corrosion along the lath direction. However, uniformly distributed film-like retained austenite hinders the further development of corrosion. The electrochemical test results show that the two-step bainite isothermal treated steel has the best corrosion resistance, and the martensitic steel has the worst corrosion resistance.

Key words： ultra-fine bainite steel heat treatment process microstructure corrosion resistance
