It has been formulated a rather simple model of martensitic unelasticity due to martensitic transformations of the first order. It is based on the idea that a martensitic reaction comes out as a mechanism of unelastic micro-strain. An equation describing the variation of the size of martensite crystals in the direct and reverse reactions has been proposed. Kinetics of these reactions is determined by two external factors: temperature and stress. Macroscopic strain is calculated by orientation
