Abstract The quasi-static and dynamic tensile behavior of Inconel 690 alloy are studied by universal material testing machine and split-Hopkinson bar. In this paper, seven batches of nickel-based alloy samples were tested. Through these tests, the tensile stress-strain curve and tensile stress-strain rate curve of the material and the corresponding failure parameters are obtained. The Johnson-Cook (J-C) dynamic constitutive model was used to fit the experimental data by batch and non-batch analysis methods. By comparing the fitting parameters of the two analysis methods, it is possible to obtain the fitting parameters without batches. This analysis method is more suitable for the actual situation.
