【摘要】：对热轧态WH610D2进行不同温度的回火处理,并对回火前后的试样进行力学性能测试和组织观察。结果表明:回火处理后,WH610D2钢的屈服强度和抗拉强度降低,伸长率升高,低温冲击韧度增加。热轧态WH610D2试样的组织以铁素体和贝氏体为主,并存在少量的马氏体,回火后的试样组织以铁素体和回火索氏体为主,并出现了少量的碳化物。
[Abstract]:The hot-rolled WH610D2 was tempered at different temperatures, and the mechanical properties and microstructure of the samples before and after tempering were tested and observed. The results showed that: after tempering treatment. The yield strength and tensile strength of WH610D2 steel decreased, the elongation increased and the impact toughness at low temperature increased. The microstructure of hot-rolled WH610D2 specimens was mainly ferrite and bainite. There is a little martensite, and the microstructure of the tempered sample is mainly ferrite and tempering Soxhlet, and a small amount of carbides appear.

【正文快照】： 随着社会对油气资源需求不断加大,我国在油气储备、运输等方面成本的投入也在不断加大[1]。我国大多采用日本的SPV50钢板作为油罐用钢,为降低对国外进口的依赖,有效地控制成本,武钢开始着力开发WH610D2钢以抵制国外的技术封锁[2-3]。该材料大多应用于大型油气机械工程,一般采
