To explore the plastic forming characteristics of TA1-Al bimetallic elbow,the critical bonding strength of the interface for the clad tube in the push-bending process was determined firstly by numerical simulation.Secondly,the effects of axial push velocity and friction coefficient on the maximum value of shear stress and the thickness distribution of the clad elbow were investigated.The simulation results show that the critical interface bond strength needed in the push-bending process is 50 MPa.Furthermore,the push velocity and the friction coefficient should be less than 10 mm/s and 0.125 for producing TA1-Al clad elbows without separation at the interface.The experimental results are approximately accordant with the simulative ones in the geometry size and thickness distribution.
