Abstract A modified Landau polynomial was proposed to describe the structure features of austenite/martensite interface under the existence of an intrfacial preferrd state. When the elastic modulus of austenite, the energy of preferred state and thdriving force for martensitic transformation were selected as the variables, a transitional platform with a slow change in order parameter, i.e. scaled shear strain whose structure is neither austenite nor martensite, was found using Ginzburg–Landau theory. The energ and width of austenite/martensite interface were calculated. Based on these calculated results, some experimental phenomena during martensitic transformatin can be explaned perfectly. It is demonstrated that the current model is more universal.
