New types of advanced high strength steels (AHSS) with advanced properties are being designed and developed through proper choice of chemical compositions and processing innovations. By changing processing parameters, number of phases such as ferrite, cementite, and martensite and their fractions can be controlled, thereby controlling mechanical properties of steels. In this work, to investigate effect of microstructure on mechanical property, a multi-phase steel was subjected to several thermal cycles involving different cooling rates using GleebleŽ that led to the evolution of different combinations of microstructure. The microstructural analysis and mechanical testing were carried out using advanced characterization tools including digital image correlation (DIC), in-situ SEM tensile tester, and electron backscatter diffraction (EBSD) before and after plastic deformation. A detailed analysis of the DIC, in-situ tensile test data, and EBSD is in-progress and will be discussed in this presentation.
