文摘

Numerical simulations of the hydroforming process of Ti/Al clad T-shapes were conducted by using finite element analysis software. These simulations were used to optimize process parameters such as internal pressure, feed distance, and friction coefficient. Subsequently, hydroforming experiments were conducted based on these simulations. The results indicated that Ti/Al clad tubes could be obtained in the practical hydroforming process under the following forming conditions: internal pressure of 110 MPa, feed distance of punches of 25 mm, and a friction coefficient of 0.1. This resulted in well-bonded micro-interface between titanium and aluminum that is free from any delamination. The protrusion height of Ti/Al clad T-shapes were 25.5 mm and had high thickness uniformity.
