Determination of local carbon content in austenite during intercritical annealing of dual phase steels by PEELS analysis

Parallel electron energy loss spectroscopy has allowed to analyse and quantify local variations in the carbon concentration of austenite islands transformed during the intercritical annealing treatment of commercial dual-phase steels. These changes in the carbon content of different austenite regions are responsible for the different volume fractions of tempered martensite, martensite and retained austenite obtained after intercritical annealing and overaging treatment. This technique reveals how carbon distribution in austenite evolves as the transformation process advances.

    The equilibrium carbon concentrations from the lever rule (calculated using the experimental martensite fractions) are shown on the same plot (open diamonds). Clearly, the scatter in the EELS carbon data increases strongly at lower annealing temperatures, in agreement with the observations of Garcia-Junceda et al. [26]. It is interesting to note that the martensite island carbon contents appear to follow a skewed distribution with a longer tail at high carbon contents.

    In terms of modeling the events, if these mechanisms are treated purely as ways to relieve the applied stress, then the obvious approach is to use the concept of critical resolved shear stress via the Schmidt factor. This approach is well known for slip and twinning; the concept of critical stress is also used in SIT [18,19], but the Schmidt factor is not considered. Another way to consider the problem is by a classic Gibbs energy approach; this is commonly used to explain TRIP [17,20] but not for twinning.

    It was worth noting that the martensite islands become dominant in HS steel, whereas such islands are mainly replaced by the decomposed martensite in HD steel. This was associated with an inhomogeneous carbon distribution in different austenite regions formed during the intercritical annealing treatment of DP steels [24]. The tempered martensite was generated by low carbon content austenite.

    A full understanding of the growth kinetics of the austenite (γ) to ferrite (α) [1–5] and the ferrite (α) to austenite (γ) phase transformations [6–8] in the intercritical region is of great interest in the production of lean Mn steels, as the austenite and ferrite condition after intercritical annealing is a key factor for kinetics of the phase transformations during further cooling [9–11].
