摘要

This paper focuses on the description of a simple kinetic model for ferrite formation in strained austenite. Based on our experimental observations in a Fe-0.16C-1.4Mn steel, this model accounts for two main contributions of the deformation in austenite to the kinetics of ferrite transformation: 1) austenite grain shape modification due to deformation and its consequences on the carbon diffusion field, which controls the growth of the ferrite layer and 2) formation of two types of ferrite, one at grain boundaries, and one inside the grains, induced by straining. This model is tuned to describe our experimental kinetics and is applied to continuous cooling and a large range of grades. Some typical results are also presented.
