Multi-phase (MP) steels fall under the category of advanced high strength steel (AHSS) that are increasingly being used for light-weighting of automotive vehicles. By changing processing parameters, number of phases and their fractions can be controlled, thereby controlling mechanical properties of MP steels. To investigate processing - microstructure – mechanical property correlation of a MP steel, thermo-mechanical processing (TMP) was performed using GleebleŽ - a TMP simulator. It was followed by microstructural analysis and mechanical testing using advanced characterization tools including digital image correlation (DIC) and in-situ SEM tensile tester. Electron backscatter diffraction (EBSD) was used before and after plastic deformation to understand crystallography of plastic deformation. The elastic behavior, strength, and ductility were determined and compared with the alloy in different processing conditions. A detailed analysis of the DIC, in-situ tensile test data, and EBSD is in-progress and will be discussed in this presentation.
