Ever since introducing the concept of Advanced High Strength Steels, Dual Phase Steel has proven to be the brightest candidate amongst the group. Owing to the simple microstructure, easy and economical production method, and its excellent strength-ductility balance, Dual Phase Steels are already being utilized in manufacturing light weight parts in the automotive industry. However, there are many scientific aspects of the subject that are still not explored. This along with the greater demand in the last few decades for initiating the use of light, strong and economically efficient steels led to wider research efforts to gain a better understanding of Dual Phase Steels. In this work, the advancements of research on Dual Phase Steel development are reviewed, with focus on the microstructural development via changes in composition and thermal treatment.
