Influence of dislocations on the spatial variation of microstructure in martensites

Original language description

Kröner's continuum theory of dislocations views each dislocation as a source of incompatibility of strains. We show that this concept can be employed efficiently in the Landau free energy functional to develop a mean-field mesoscopic model of materials with dislocations. The order parameters that represent the distortion of the parent phase are written in terms of elastic strains which are themselves coupled by incompatibility constraints. Since the ?strength of the incompatibility depends on the localdensity of dislocations, the presence of dislocations affects the evolution of the microstructure and vice versa. An advantage of this formulation is that long-range anisotropic interactions between dislocations appear naturally in the formulation of thefree energy. This novel field-theoretical approach helps to bridge the gap in studying the behavior of materials at the length and time scales that are not attainable by atomistic or macroscopic models.
