Nanostructured Aluminum and IF Steel Produced by Rolling—a Comparative Study

Abstract

In a comparative study aluminum and interstitial free (IF) steel have been deformed to very large strain by cold rolling and accumulative roll bonding. The deformation microstructure has been analyzed by transmission electron microscope techniques and microstructural parameters have been quantified together with mechanical properties. An analysis of the strain induced change in structure, strength and ductility has shown a very similar behavior for the two materials and also that their mechanical properties can be optimized by introducing a new processing step, post-process deformation.
