Phase Transformations of Nanocrystalline Martensitic Materials
MRS Bulletin, 2009AbstractThe physical phenomena and engineering applications of martensitic phase transformations are the focus of intense ongoing research. The martensitic phase transformation and functional properties such as the shape-memory effect and superelasticity are strongly affected by the crystal size at the nanoscale.

Adaptive phase formation in martensitic transformation
Physical Review B, 1991It is shown that an appearance of an intermediate martensite phase called adaptive martensite may be expected if the surface energy of a boundary between two orientational variants of the normal martensite phase is very low and the typical lattice-mismatch-related elastic energy is high.

IMPACT OF THE ORIGINATING MARTENSITIC PHASE ON THE CHARACTER OF MARTENSITIC PHASE TRANSFORMATION
Anali PAZU, 2023In the article, we discuss the influence of the locally perturbed order parameter in austenitic-martensitic phase transformation on the character of the phase transformation. We choose Landau type mean field approximation which covers the most important features of the proposed theoretical description.

A review on phase field modeling of martensitic phase transformation
Computational Materials Science, 2013In the last few decades, the phase field method has shown tremendous capabilities of predicting microstructure evolutions at the mesoscale scale. This method was widely used for modeling martensitic phase transformation, where the displacive character was a challenging problem for the counterpart sharp interface approach.

Abstract A generalization of the phase-field theory for multivariant martensitic phase transformations is suggested that allows one to vary martensite–martensite interface energy independent of energy for austenite–martensite interfaces. The finite element method is utilized to solve the coupled phase-field and elasticity equations. Width and energy of

The Effect of Pressure on Martensitic Phase Transformations
Advances in Science and Technology, 2012Stability of the crystal structure is determined by the competition between attractive and repulsive interatomic forces. Using many-body exponential potentials it can be shown that the bcc structure corresponding to austenitic phases is more stable for low values of the q-parameter characterising the attractive forces for a fixed value of the p ...
