MARTENSITIC TRANSFORMATION AND ELASTIC CONSTANTS

Abstract
The deformation energy barrier for the martensitic transformation is estimated from the data of the elastic constants. The deformation energy barrier for B.C.C → F.C.C martensitic transformation is, at most, of the order of the thermal energy at room temperature. The deformation energy barrier between B.C.C. and F.C.C can be surmounted by thermal energy at temperatures higher than Ms. The martensitic transformation is proposed to be understood as the freezing process of the non-linear lattice vibration, i.e. solitons, instead of the soft phonons.
