Adaptive phase formation in martensitic transformation

Physical Review B, 1991
It 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.

Phase-field approach to martensitic phase transformations: Effect of martensite–martensite interface energy

International Journal of Materials Research, 2011
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

Modeling of martensitic phase transformation accounting for inertia effects

International Journal of Mechanical Sciences
As a diffusionless phase transformation, martensite evolves at the speed close to sound, with its kinetics and morphology dominated by the mechanical energy.

The Effect of Pressure on Martensitic Phase Transformations

Advances in Science and Technology, 2012
Stability 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 ...

Thermodynamic modeling of martensitic phase transformations

SPIE Proceedings, 2010
The unusual properties of shape memory alloys (SMAs) are due to solid-to-solid martensitic phase transformations (MPTs) which correspond to a lattice level instability of the crystal structure. The high temperature phase is usually a high symmetry structure and is called the austenite phase whereas the low temperature phase has a low symmetry and is

On the nature of the martensitic phase transformation in lithium

Solid State Communications, 1970
Abstract Using a nonlocal Phillips-Kleinman pseudopotential we discuss the thermodynamic features of the martensitic phase transformation of lithium. Reasonable agreement for the transformation temperature is obtained.

Martensitic Phase Transformation

2020
This chapter provides a summary of basic knowledge on martensitic phase transformation in general and in steels, in particular. Besides the thermodynamic aspects of martensitic phase transformation, the different transformation path’s (direct γ to α’, direct γ to e, direct e to α’ and indirect γ to e to α’) occurring in steels are described in detail ...

Is the olivine–spinel phase transformation martensitic?

Nature, 1982
Olivine, the dominant mineral in the Earth's uppermost mantle, undergoes one, or possibly a series of phase transformations to adopt a spinel structure at pressures above ∼13 GPa. The mechanism by which the transformation is accomplished could have important implications for understanding mantle dynamics and deep focus earthquakes.
