title = "Size Effect on Cyclic Deformation Behavior and Springback Prediction of Ultrathin Superalloy Sheet",
abstract = "Springback is a challenging issue in the processing of ultrathin superalloy components whose thickness are usually in the range of 0.1 \textasciitilde{} 0.3 mm, and its prediction is affected by the size effect. In this research, the cyclic shearing tests of superalloy sheets with different grain sizes were performed to clarify the relation between size effect and cyclic deformation behavior. The experimental results indicated that it is affected by the geometrical and grain size effects. To explore how the size effect affects the springback of ultrathin superalloy sheet, U-bending tests were performed on specimens with different grain sizes and thicknesses. In addition, different hardening models were compared by multiscale U-bending tests. The results showed that the Yoshida–Uemori (YU) model can well describe the cyclic deformation of superalloy sheet at various scales.",
