Composite materials and layered alloys have become an interesting topic in materials development. The roll bonding (RB) process as a solid phase method of bonding has been widely used in the manufacturing of layered strips. The poor bond strength is one of the major drawbacks of the RB process. In the present study, Pb particles were used to enhance the bond strength between aluminum strips as filler material. AA1050 particle-reinforced sheets with different contents of interlayer Pb particles were fabricated at various rolling temperatures and thickness reduction ratios. Effects of roll bonding parameters that create successful bonds such as amount of Pb particle content, plastic strain from rolling process and rolling temperature were investigated. The bond strength was evaluated by the peeling test. It was found that by increasing the rolling temperature, thickness reduction ratio and Pb content, successful bonds with higher strength were created. Scanning electron microscopy was utilized to characterize the peeled surface of AA1050/Pb samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
