Stress-strain partitioning analysis in dual phase steels
Dual-Phase (DP) steels are made of ductile ferrite phase and hard martensite phase. Although it became crucial in progress of automotive industry to save fuel consumption and reduce total weight of vehicles, we need more accurate estimation of distribution to mechanical properties in total amounts of specimen. DP steels have considerable difference of mechanical levels in each phase including ferrite and martensite. That is why this study focuses on deconvolution of experimental tensile curve into ferrite and martensite using EBSD for calculation of phase volume fractions and Swift equation. Nanoindentation for certain parameter of each phase was conducted to produce the deconvolution curves.
