The martensite phase formation in elastic fields of isolated screw and edge dislocations, as well as in planar clusters of like-sign dislocations and in a 2-dimensional network of opposite-sign edge dislocations, was quantitatively analyzed within the theory of smeared martensitic transitions. The heterogeneous nucleation of martensite at dislocations was shown to increase the characteristic temperature of the martensitic transition and its temperature smearing.
