    In this study, three different microstructures of dual-phase (DP) steel obtained by varying the intercritical annealing temperature were observed three dimensionally by a serial-sectioning method and their metrics and topological properties were quantified. The results demonstrated that martensite in DP steels has various morphologies such as layers, particles, holes, and voids. The fraction of these characteristic morphologies was examined as a function of the intercritical annealing temperature.
