The presence of ceramic particles between metal strips in metal matrix composite processing by roll bonding affects their bonding properties. In this study, roll bonding of commercial pure aluminum (AA1100) strips in the presence of various B4C contents at different thickness reductions was focused. Furthermore, the effect of rolling temperature (at ambient temperature and 473 K) on the bonding properties of the strips was investigated via peeling tests. The results showed that the presence of the B4C particles between the aluminum strips reduces the bond strength and weld efficiency; in contrast, they are increased by increasing temperature. Therefore, by increasing temperature it is possible to use the higher amounts of the B4C particles between the aluminum strips.
