As a diffusionless phase transformation, martensite evolves at the speed close to sound, with its kinetics and morphology dominated by mechanical energy. However, mechanism of martensitic transformation consideration inertia is rarely investigated. This paper presents multiphase-field model, where strain in performs as wave source, return kinetic energy contributes driving force for transformation. result, fields, i.e., stress velocity, are derived according increment strain. The propagation direction corrected considering growth nucleus. With 1D 2D analysis, well comparison against static case, investigated, advantage model accounting effects illustrated.
