This article represents the results of studies related to the production of tri-layer composites by tailoring the initial materials characteristics before explosive welding and cold rolling process. It is shown that the similarity of mechanical characteristics during simultaneous deformation of dissimilar layers reduces the differential velocity between the core and clads as indicated by lower failure propensity. Using the appropriate thickness reductions and in turn the high interfacial bond aids the sound flow over a wide range of processing conditions. The non-uniformities of deformation would be accommodated by the softer layer near the interface through micro-mechanical interactions. In addition, the difference in the plastic strain experienced by each material increases with increase in the total plastic strain and volume ratio.
