The mechanical properties of Ferrite-Martensite dual phase steels are affected by microstructural factors, such as, martensite volume fractions, grain size of ferrite, hardness ratio of Ferrite-Martensite, connectivity and chemical components etc. Therefore, this study has been made on the influence of Impact fracture behavior which changes the hardness ratio of Ferrite-Martensite by mean of heat treatment of low carbon Mn-Steels. In order to analyze and examine the effect of fracture behavior under impact load, this study investigated the impact strength, the impact loading time, the absorbed energy on the fracture ductility of Ferrite-Martensite dual phase steels, the formation of micro crack and slip, and plastic restraint of martensite on the plastic deformation.
