Abstract：

In order to explore the formability of Fe/Al clad tube in hydro\|bulging process, the finite element method（FEM） was used. The distribution of the thinning ratio of wall at different fluid pressures and friction coefficients was discussed by numerical simulation and the difference of thinning ratio distribution between the pure Fe layer and pure Al layer was found out. With the help of the calculated results, the hydro-bulging process was performed and the Fe/Al clad tube T-shape was fabricated successfully. The results show that the bonding of the interface of Fe/Al clad tube is well, and the quality improvement of the Fe/Al clad tube T-shape can be achieved by regulating the fluid pressure and friction coefficient.
