Dual-phase (DP) steels derive their perfect blend of properties via the hard second phase, namely
martensite or bainite in a softer ferrite matrix. The key to refine the mechanical properties of DP steels
rests on optimizing and tailoring the distribution and size of the hard second phase present in the ferrite
matrix. There can be several combinations of processing routes depending on the governing
mechanisms, such as recrystallization, pearlite dissolution, phase transformation, etc., which can affect
the morphology and distribution of martensite phase present in DP microstructures. All these
mechanisms are invoked at various stages of annealing process cycle. In the present study, experimental
simulation of various annealing parameters was carried out on a cold-rolled steel using a custom
designed annealing simulator. The evolution of microstructure was studied by field emission scanning
electron microscope. The evolving microstructures were correlated with governing mechanisms of
recrystallization, pearlite dissolution, and phase transformation. Through these simulations, it was
possible to tailor the microstructure and consequently improve the tensile properties of the DP steel.
