Martensitic phase transformations and shape memory alloys

Current Opinion in Solid State and Materials Science, 1996
Abstract Recent advances in the field of martensitic phase transformation include the proposal of a unified theory to explain both isothermal and athermal martensitic transformations, further development of the short-range ordering models for rubber-like behavior, further elucidation of the pseudo-elastic properties of ceramics, and refinement of the

Martensitic transformation onset in noble metal β phase alloys

Journal of Physics F: Metal Physics, 1982
The martensitic phase transition onset is studied for noble metal binary beta brasses. The transformation mechanism, which is electronic, is determined by electron-phonon coupling in such metals. The composition dependence of structure stability is investigated, together with the connected role of ternary additions to the alloys.

Martensitic phase transformation and lattice dynamics of fcc cobalt

Physical Review B, 1996
The phonon dispersion of the high-temperature fcc phase of pure cobalt has been measured by inelastic neutron scattering at 833 K. Transverse phonon branches were measured above and below the Martensitic hcp-fcc transformation in order to learn about an influence of lattice dynamics, if any.

Elasto-plastic phase-field simulation of martensitic transformation in lath martensite steels

Philosophical Magazine, 2013
Phase-field simulation of lath martensite formation in Fe–0.1C mass% steel was carried out based on the two types of slip deformation (TTSD) model, which is recently developed as a result of analyt...

A review on phase field modeling of martensitic phase transformation

Computational Materials Science, 2013
In 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.

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 ...

Multi-scale phase field approach to martensitic transformations

Materials Science and Engineering: A, 2006
Abstract Because of its flexibility in treating complex geometries and topological changes, the phase field method has been used widely in modeling microstructural evolution during various phase transformations, grain growth and, most recently, plastic deformations.

Martensitic Transformation as a Typical Phase Transformation in Solids

1978
Publisher Summary The chapter presents a discussion on martensitic transformation as a typical phase transformation in solids. Martensitic transformation is a polymorphic phase transition in solids consisting of the regular rearrangement of the crystal lattice, the constituent atoms of which do not interchange places.

The first-order phase transformation in NaCN: A martensite transformation

Journal of Applied Physics, 1983
The first-order phase transformation in NaCN at 288 °K is identified as a martensite transformation accompanied by the formation of mechanical deformation twins of the first kind. Photomicroscopy measurements of the crystal surface morphology and nuclear magnetic resonance measurements of the domain orientation are in agreement with the predictions of ...

Phase-field theory for martensitic phase transformations at large strains

International Journal of Plasticity, 2013
Abstract General phase-field theory for multivariant martensitic phase transformations and explicit models are formulated at large strains. Each order parameter is unambiguously related to the transformation strain of the corresponding variant. Thermodynamic potential includes energy related to the gradient of the order parameters that mimics the ...
