The development of dual phase steels to meet the current world demands, for the purpose of decreasing the fuel consumption with increasing the strength to weight ratio, requires certain microstructural modifications. In the present research, a new morphology of DP steel, known as Laminated DP steel, as well as its unique production method has been introduced. The new process developed involved properly selecting low carbon steels, stacking them in a laminated manner and performing a roll bonding process followed by short austenitization treatment. The martensite volume fraction was designed and obtained to be 24%. Scanning electron microscopy (SEM) was employed for microstructural examination. Moreover, deformation and tensile behavior of the newly developed steel were studied and compared with those of some ordinary DP steel (ODP). Room temperature uniaxial tensile tests also revealed mechanical properties
