2018, Acta MaterialiaCitation Excerpt :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.
Twinning and Tripping in 10% Mn steels
2014, Materials Science and Engineering: ACitation Excerpt :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.
Influence of nanoparticle reinforcements on the strengthening mechanisms of an ultrafine-grained dual phase steel containing titanium
2013, Materials and DesignCitation Excerpt :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.
Application of cyclic partial phase transformations for identifying kinetic transitions during solid-state phase transformations: Experiments and modeling
2011, Acta MaterialiaCitation Excerpt :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].
