dc.description.abstractThis work has the main purpose of analyzing the intercritical annealing time on the microstructure transformation kinetics of a dual-phase steel. Computational simulations confirmed the experimental observation, showing that annealing time at 755°C influences the formation of the austeno-ferri tic microstructure, and this can be attributed to the alloying elements partition and redistribution through ferrite-austenite interfaces. Kinetics calculations using a spherical model of diffusion, and a unidimensional model with bi-directional diffusion flux, resulted in equivalent results, which can partially describe the observed kinetics of transformation. Determination of basic metallographic parameters of the as-received material (martensite fraction and mean intercept), together to the knowledge of alloy elements distribution, are prerequisites to the success of the computational simulation.
