摘要
使用UG建立三维模型,有限元分析软件ANSYS进行不同温度下的1Cr18Ni9Ti不锈钢离子氮化过程中的温度场、应力场以及应变场的数值模拟。模拟结果表明,不同氮化温度得到的温度场分布均匀,随着氮化温度由440℃增大到520℃,模拟过程内应力由0.0052MPa提高至0.0061MPa,应变由0.14增大到0.17。获得了1Cr18Ni9Ti不锈钢螺纹离子氮化的最佳工艺参数为:渗氮温度440℃、保温时间6h、气压600Pa。
The three-dimensional model was established by UG,and the finite element analysis software ANSYS was used to perform numerical simulations of the temperature field,stress field and strain field of 1Cr18Ni9Ti stainless steel during ion nitriding at different temperatures.The simulation results showed that the temperature fields obtained at different nitriding temperatures were uniformly distributed,and the internal stress of the simulated process increased from 0.0052 MPa to 0.0061 MPa and the strain increased from 0.14 to 0.17 as the nitriding temperature increased from 440°C to 520°C.The optimum process parameters for ion nitriding of 1Cr18Ni9Ti stainless steel threads were obtained as follows:nitriding temperature 440°C,holding time 6 h,and air pressure 600 Pa.
