摘要：

基于循环加载-卸载和循环剪切试验，研究了0.2 mm厚的GH4169高温合金超薄板的循环塑性变形行为，评估了不同强化模型的预测精度。结果表明，GH4169高温合金超薄板在循环塑性变形过程中的弹性模量衰减了19%，YU模型能够有效表征GH4169高温合金超薄板的循环力学响应行为。U形弯曲和封严环液压成形工艺过程的仿真表明，YU模型对于回弹的预测精度高于AF和各向同性模型。基于YU模型和型面补偿方法可使封严环的正向和反向回弹量分别降低52.2%和68.1%。

Based on the cyclic loading and unloading and the cyclic shearing tests, the cyclic plastic deformation behavior of superalloy GH4169 ultra-thin sheet with the thickness of 0.2 mm was investigated, and the prediction accuracy of different hardening models was evaluated respectively. The results show that the elastic modulus of superalloy GH4169 ultra-thin sheet decreases by 19% during cyclic plastic deformation process, and the Y-U model can effectively characterize the cyclic mechanical response behavior of superalloy GH4169 ultra-thin sheet. The simulation of U-bending and hydroforming process of sealing ring indicates that the prediction accuracy of Y-U model for springback is higher than that of A-F and isotropic models, and based on the Y-U model and the profile compensation method, the forward and reverse springback amounts of sealing ring can be reduced by 52.2% and 68.1%, respectively.
