Abstract：

The indium nickel alloy Inconel is a common raw material of grid straps for fuel assemblies in nuclear power plants. In order to improve the product quality, the stamping formability of the indiumnickel alloy sheet was studied. In view of the expensive and anisotropic characteristics of the indiumnickel alloy, the forming properties of indiumnickel alloy were studied by finite element numerical simulation. First, the mechanical properties of materials were obtained by the experimental method. Then, the forming properties of indiumnickel alloy under the condition of variable speed and variable loading were simulated by finite element method, and the influences of forming speed, velocity mode, blank holder force and load mode on the forming properties of indiumnickel alloy were analyzed. Finally, the correctness of numerical simulation was verified by die stamping test. The results show that the analysis of finite element numerical simulation gives a deep understanding of the formability of indium nickel alloy sheet and provides the technological parameters for the stamping process of grid straps.
