Kinetics on the micro- and macro-levels in polycrystalline alloy materials during martensitic transformation
The authors study from the thermomechanical point of view the kinetics during the martensitic transformation on the micro- and macro-levels in polycrystalline alloy materials. First, the authors consider a model of the polycrystalline alloy materials. The micro-fraction and the macro-fraction are defined. It is shown that the evolution of the macro-fraction during thermomechanical loading is governed by a differential equation. Then, the authors prove that the rate of the macroscopic transformation strain is proportional to the transformation rate. Illustrative examples and diagrams are presented.
