“…There have been various difficulties and limitations in the process through which these materials are bonded to fabricate bimetal or multi-metal sheets. Shajari et al [31] investigate the Al-Cu cold rolling process, the bonding mechanism of metallic layers during CRB, and the effect of the roll bond strength parameters such as initial thickness, for one. They show roll bonding has three stages: (1) physical touch; (2) activating surfaces in touch;…”

This study investigates the mechanical properties and microstructural characteristics of explosion-welded Al/Cu two-layer strips during the ECAR process using finite element simulations and experiments. Furthermore, the explosion-welded Al/Cu two-layer strip was examined with various configurations to determine the effects of die angle and friction coefficient on the distributions of effective strain and stress. In addition, the experimental and computational approaches were utilized to explore the ECAR process in two routes, RA and RC, for three directions. Finite element simulations were run and validated using experimental data. The findings show that the ECAR method is effective to enhance the mechanical characteristics of the strips. Moreover, the obtained results represent that the ECAR process reduced the size of the grains. Furthermore, it was shown that by increasing the number of routes in the ECAR process, the stress values were increased. However, the ductility of the two-layer strip was decreased. According to the current study, the route and the number of routes used in the ECAR process have a considerable effect on the strength of the two-layer strip.
