Estimating interface bonding strength in clad sheets based on tensile test results

Highlights Correlating the tensile test to peel test results by simple calculations. The drops in flow stress after the UTS are related to debonding of the interfaces. Presence of strain-induced martensite enhances the strength of the composite sheets.
Abstract The bond strengths of the three-layered aluminum/stainless steel/aluminum composite clad sheets produced by cold roll bonding were estimated by the tensile test results. The developed procedure was based on the drops in flow stress after the maximum point of the stress–strain curves, which are related to debonding of interfaces and signify the effect of bond strength on the tensile behavior. The shape of the stress–strain curve of a specimen heat treated at 600°C to form a brittle intermetallic layer at the roll bonding interface was found to be analogous to those obtained from the tensile test of conventional one-layer specimens, which was considered to be a good evidence of interface debonding during tensile test of roll bonded sheets that show sharp flow stress drops. An important contribution of this work is correlating the tension test to peel test results by simple calculations based on the principles of mechanics of materials.
