本文通过生产中的具体实例,介绍了热轧含钛16Mn钢板中导致性能不合格的几种异常显微组织——大颗粒的Ti(C,N)、晶粒粗大、粒状贝氏体和锰偏析带。具有这类组织的钢板,在经过正火处理后,因实际晶粒的显著细化,都达到了强韧化的目的。说明正火处理的含钛16Mn钢板能满足锅炉、容器制造业对专用钢的高质量要求。 In this paper, through the concrete examples in production, several abnormal microstructures, such as large grain Ti (C, N), coarse grain, granular bainite and manganese Segregation zone. With such organizations of the plate, after normalizing, the actual grain significantly refined, have reached the purpose of toughening. Description of normalized titanium 16Mn steel to meet the boiler, container manufacturing industry for high-quality steel requirements.
