| 摘 要： | 研究了20Cr3MnMoV钢热处理工艺参数对力学性能和渗氮硬化性能的影响。结果表明:20Cr3MnMoV钢热处理由固溶处理、时效、预时效和渗氮组成。合理控制时效过程是20Cr3MnMoV钢热处理的主要工艺特点。分别采用固溶处理后充分时效,无预时效直接渗氮和先预时效再渗氮等多种工艺,可以适应于不同工作条件的模具和构件,以满足耐磨性和强韧性的不同要求。20Cr3MnMoV钢氮碳共渗处理,可实现快速渗氮,深层渗氮硬化和基体强化,有广泛应用前景。

| Abstract: | Effect of heat treatment process parameters on the mechanical properties and nitriding hardening properties of 20Cr3MnMoV steel was investigated.The results show that the heat treatment of the 20Cr3MnMoV steel is composed of solid solution treatment,aging,preaging and nitriding.Reasonable controlling the aging process is the main technological characteristics of the heat treatment of the 20Cr3MnMoV steel.By using respectively solid solution treatment+full aging,nitriding without preaging,and preaging+nitriding,it can be adapted for dies and components at different working conditions,so that it satisfies the different requirements of wear resistance and strength-ductility.Nitrocarburizing of 20Cr3MnMoV steel can be used to realize fast nitriding,deep layer nitriding-hardening,and matrix hardening,which has wide-spread prospects of application. |
