摘要
利用光学显微镜、扫描电镜、室温拉伸、室温冲击检测等方法研究了 Si、V、Ti这3种合金元素对40Cr13马氏体不锈钢显微组织与力学性能的影响.结果表明,在40Cr13马氏体不锈钢中同时加入V、Ti合金元素有效抑制了(Fe,Cr)23C6类型碳化物的析出;在40Cr13马氏体不锈钢中,通过提高Si元素的含量,能有效地提高试验钢的硬度和冲击性能;加入0.21％V能够提高40Cr13马氏体不锈钢的强度和硬度,但加入0.21％Ti使得40Cr13马氏体不锈钢的强度和硬度有所下降;V、Ti合金元素的同时加入,使得40Cr13马氏体不锈钢抗拉强度和屈服强度略微有所降低,但能有效提高40Cr13钢的冲击性能.
Abstract
Effects of Si,V and Ti alloying elements on the microstructure and mechanical properties of 40Cr13 martensitic stainless steel were studied by means of optical microscope,scanning electron microscope,room temperature tensile test and room temperature impact test.The results show that the addition of V and Ti alloy elements to the 40Cr13 martensitic stainless steel effectively inhibit the precipitation of(Fe,Cr)23C6 carbides.The hardness and impact property of the 40Cr13 martensitic stainless steel are effectively improved by increasing the content of Si element.The addition of 0.21％V improves the strength and hardness of the 40Cr13 martensitic stainless steel,but the addition of 0.21％Ti reduces the strength and hardness of the 40Cr13 martensitic stainless steel.The addition of V and Ti alloy elements at the same time reduces the tensile strength and yield strength of the 40Cr13 martensitic stainless steel slightly,but improves the impact toughness of the 40Cr13 steel effectively.
