摘要
马氏体不锈钢以其优异的强度和硬度特性,在许多工业应用中占据重要地位,尤其是在耐磨性和抗腐蚀性要求极高的环境中.为了进一步满足该试验材料在高压高温条件下的服役性能,试验提出研究淬火热处理对06Cr11Ni2MoVNb2马氏体不锈钢微观组织和宏观性能的影响,通过微观组织、拉伸性能和力学性能3个方面对比分析了不同冷却方式与淬火温度对试验钢组织与性能的影响.结果表明:对钢体进行淬火后得到的钢组织主要为板条状的马氏体、冷却奥氏体以及碳化物,淬火温度为1040℃时,试验钢的综合性能最为优越,说明不同冷却方式与淬火温度对试样钢的性能和组织有着十分显著的影响.
Abstract
Martensitic stainless steel plays an important role in many industrial applications due to its excellent strength and hardness characteristics,especially in environments with extremely high requirements for wear resistance and corrosion resistance.In order to further meet the service performance of the test material under high pressure and high temperature conditions,the experiment proposes to study the effect of quenching heat treatment on the microstructure and macroscopic properties of 06Cr11Ni2MoVNb2 martensitic stainless steel.The effects of different cooling methods and quenching temperatures on the microstructure and properties of the test steel were compared and analyzed from three aspects:microstructure,tensile properties,and mechanical properties.The results show that the steel structure obtained by quenching the steel body is mainly lath martensite,cooled austenite and carbide.When the quenching temperature is 1040 ℃,the comprehensive properties of the test steel are the best,which indicates that different cooling methods and quenching temperatures have a very significant impact on the properties and structures of the sample steel.
