In this paper a nanoscale model of the transformation-induced plasticity in a single crystal is introduced. Scale of averaging of physical phenomena is considered between 10-9 m and 10-8 m. Then, single martensite variants and interfaces are distinguished in description of the martensitic transformation. Furthermore, single slip surfaces are introduced for the description of plasticity. Modelling of these phenomena in such a small scale allows taking into account precise interactions between them. The central part of the discussed model is the free energy. Form of this function is introduced by means of a set of geometrical objects distinguished within the crystal structure. Conditions for slip initiation and martensitic transformation are defined with the aid of free energy. Qualitative role of shuffles in the transformation-induced plasticity is discussed.
