Relationship between microscopic morphology and mechanical behaviors has been examined with numerical analyses and experimental tests for Ferrite-Pearlite dual component steels characterized with different volume fractions of Pearlite microstructure. In the numerical analyses, three types of microscopic morphology have been modeled with finite elements and the deformation state of the finite element model has been computed by means of finite element analysis based on mathematical homogenization method. For experimental tests, specimens of some volume fraction of Pearlite have been made under adjusting strengthening factors except the volume fraction of Pearlite as much as possible. By comparing these numerical and experimental results, the effect of the microscopic topology to macroscopic mechanical behavior has been discussed in this study.
