The computational modeling of nonequilibrium thermodynamics of the martensitic transformations

Abstract A mathematical model describing the thermodynamic properties of martensitic crystals is introduced. The thermodynamic model uses the elastic energy derived from the Ericksen-James theory and it incorporates a heat-flux which couples the temperature gradient with the underlying lattice structure. The presented numerical computations simulate thermal effects during the development of the martensitic lamellae from an unstable deformation of the martensitic crystal. The micro-thermal structures are observed to accompany the development of the martensite.
