摘要

摘要: 对GH4169高温合金开展了不同应力三轴度（-0.33~0.33）、不同应变率（0.001~5 000 s^-1）、不同温度（293~1 073 K）条件下的材料性能试验.基于Johnson-Cook失效模型的框架，研究了Johnson-Cook(JC)失效模型及已有文献提出的修改形式中应力三轴度项拟合结果的不确定性及应变率对失效应变的线性关系描述局限性问题，通过提出的特定参数确定方法与耦合应力三轴度的应变率效应指数函数，建立了一种唯象修正的失效模型.基于GH4169高温合金的试验结果，标定了修正的失效模型与JC模型中各个参数.结果表明：在不同应力三轴度下，GH4169的失效应变表现出不同的应变率效应；与传统的JC模型相比，修正的失效模型更能够较好地描述GH4169的失效行为；同时能够保证失效应变的非负性.

Abstract: The material property tests of superalloy GH4169 were carried out under different stress triaxialities (-0.33~0.33), different strain rates (0.001~5 000 s^{-1^{) and different temperatures (293~1 073 K). Under the framework of the Johnson-Cook (JC) failure model, the uncertainty of fitting results of the stress triaxiality term in the JC failure model and the limitation of the linear relationship description between the strain rate and the failure strain in the modified form proposed in previous literatures were studied. With the proposed method of calibrating specific parameters and the strain rate effect index function of coupled stress triaxiality, a phenomenological modified failure model was established. Based on the test results of superalloy GH4169, the parameters of the modified failure model and the JC model were calibrated. The results show that, the failure strain of GH4169 exhibits different strain rate effects under different stress triaxialities; the modified failure model can better describe the failure behavior of GH4169 than the traditional JC model; at the same time ensure non-negativity of the failure strain.}}
