Study on microalloying and heat treatment process of spring steel 55SiCrV

  • 摘要: 在弹簧钢55SiCr成分基础上进行钒微合金化处理,获得了55SiCrV,通过淬火+回火正交试验、显微组织观察、力学性能测试和X射线衍射等手段,研究并分析了淬火+回火工艺对弹簧钢55SiCrV微观组织和力学性能的影响,结果表明:0.20%V的添加可使55SiCrV组织中存在大量弥散均匀分布的10~35 nm含钒析出相,强化效果最佳。淬火+回火处理可以改变55SiCrV的显微组织比例,其中的残余奥氏体可以降低强度和增加塑性,55SiCrV获得最佳力学性能匹配(Rm=1 815 MPa、Z=28%)的热处理工艺为900 ℃淬火+430 ℃回火,对应其残余奥氏体含量为2.3%。
