Bond strength of cold roll bonded Al layers with and without Ti particles was studied. The effect of particle’s content that was placed between aluminium sheets and rolling reduction on weld efficiency and bonding was studied. Peel test was used to measure the adhesive strength between the bonded Al strips. The weld efficiency η of the roll bonding process was calculated. The results showed that the weld efficiency in the presence of Ti is lower than that in the absence of Ti. The surface conditions of the peeled surfaces were inspected by scanning electron microscopy. It could be concluded that by enhancing the rolling reduction up to 70%, the bonded area on the interface is increased and bonds with higher strength are produced. However, the addition of Ti particles leads to reduction of the bonded area and bond strength. Also, presence of Ti powders up to 0.5 wt%, lead to the increase of threshold deformation to 45%.
