Coordinated deformation and mechanical properties of titanium/aluminum clad plates rolled at different temperatures by moving induction heating
A new method of rolling titanium/aluminum clad plate by moving induction heating at different temperatures was proposed.The moving titanium plate was heated by electromagnetic induction alone and rolled with room temperature aluminum plate to realize the coordinated deformation of titanium and aluminum,for improving the bonding strength of the clad plate.ANSYS finite element software was used to simulate the temperature change process of a titanium plate in the process of moving induction heating,to ensure that the temperature distribution of titanium plate along the width direction was uniform at the entrance position of the roll.Based on the finite element simulation results,the moving speed and induction heating parameters of the titanium plate were determined,and the composite experiments of moving induction heating and rolling were carried out to study the influence of different reductions on the coordinated deformation and bonding strength of titanium/aluminum clad plate.The results show that with the increase of reduction rate,the difference of Ti/Al deformation rate first decreases and then increases.When the rolling reduction is 39.4%,the rolling deformation rate of Ti/Al is basically the same,the rolling clad plate is straight,the interfacial shear strength is the highest,reaching 124.6 MPa,and the shear fracture occurs on the aluminum substrate.
