| 摘 要： | 对两种不同成分的C-Mn-Mo系低合金高强钢(HSLA)进行拉伸和冲击试验,采用光学显微镜和扫描电子显微镜观察试验钢种的微观组织,分析Mo和B对HSLA钢组织和性能的影响.结果表明,通过控制钢种的成分和工艺,可得到具有高强度、高韧性匹配的C-Mn-Mo系HSLA钢,钢种具有贝氏体组织;在C-Mn-Mo系HSLA钢中,适当增加Mo和B的含量,可以明显提高钢种的强度,且不损害其塑韧性.

| Abstract: | The mechanical properties of two kinds of HSLA steels with C-Mn-Mo content are analyzed by the tensile test and impact test.Optical microscope and scanning electron microscope(SEM) are used to observe the microstructure of the steels.The effects of Mo and B on the mechanical properties and microstructure are discussed.The results show that the C-Mn-Mo HSLA steels have high strength,good plasticity and good ductility and their microstructures are bainite.The increase of Mo and B leads to improved strength ye... |
