Corporative and coherent effect of Martensite transformation

The martensite transformation is studied in this article using the Landau theory. The whole transformation material including martensite and residual austenite is considered. We conclude that the transformation temperature Ms, its variation versus the carbon concentration and the T-dependence of the fraction of martensite formed x. In our model there is no energy barrier problem. The results are consistent with the experiment. (author). 9 refs, 2 figs
