Cold roll bonding process, as a solid phase method of bonding same or different metals by rolling. In this study, for the first time, formability of two-layer aluminum strips fabricated by the CRB process are investigated by Nakazima tests and experimental. To produce two-layer aluminum strips using a rolling machine and apply thickness reduction was %50 at room temperature. Mechanical properties, tensile fracture surfaces were studied and compared. It was observed that strength and microhardness 149.5 and 80% increased respectively, but elongation and ductility decreased compared to the initial strip due to strain hardening and cold work. Also results of SEM demonstrated that after CRB process, ductile fracture accompanied by dimples samples and shear zones were observed.
