In recent years, bimetallic strips have been increasingly used in manufacturing for various purposes. The rolling process is a popular method for producing bimetallic strips. This study proposes a new analytical model based on the slab method to predict the bond strength of two layer strips. Results show that increasing the thickness reduction during rolling improves the bond strength. Finite element simulation and experimental study further validate the results obtained from the new analytical model for producing AA1060/AA7075 bimetallic strips. Additionally, the proposed analytical model is suitable for modeling the roll bonding process of two-layer strips, and it contributes to our understanding and production of bimetal strips. Scanning electron microscopy (SEM) was used to investigate the peeled surface of the samples.
In recent years, bimetallic strips have been progressively used in manufacturing to make collective purposes. Amongst cladding approaches, the rolling process is one of the most popular processes in making bimetallic strips. In this study, a new analytical model based on the slab method has been proposed to predict the bond strength of two layer strips. Results show that the bond strength of strips increases with increasing total rolling thickness reduction of the samples. Also, the finite element simulation and an experimental study were run to approve the results obtained from the new analytical model for producing AA1060/AA7075 bimetallic strips. Moreover, the planned analytical model is appropriate for modeling the roll bonding process of the two-layer strips and it is proficient to extend our information in engineering and production of bimetal strips. The bonding strength of bilayer samples enhanced by increasing the reduction in thickness ratio. The peeled surface of samples has been investigated using scanning electron microscopy (SEM).
