摘　　要：研究了1Cr18Ni9Ti合金钢,在高温时效处理状态下的微蠕变粘弹性力学性质,为工程实际提供粘弹性力学参数。以应变电测量的方法在1Cr18Ni9Ti试样表面沿轴线粘贴标距为50mm的胶基泊式电阻应变片,在电子万能试验机上对试样施加一恒应力,以静态电阻应变仪测量试样的微蠕变,240min蠕变量为0.088%。说明1Cr18Ni9Ti合金钢具有一定的粘弹性力学性质。Research of the Micro-mechanical properties of viscoelastic creep of the 1Cr18Ni9Ti Steel which under the high temperature aging treatment. Provide visco-elastic parameters for en- gineering. Stick plastic-based Park-resistance strain gages of distance 50mm on the sample surface along the axis paste using strain measurement method. Use the electronic universal testing machine to impose a sample constant stress on the sample, and use the static resistance strain meas- urement to test sample micro-creep of the sample. The creep of 240 minutes of the 1Cr18NigTi sample is0. 088 %. Conclusion：the 1Crl8NigTi have the mechanical properties of viscoelastic.
