Thermodynamic modeling of martensitic phase transformations
SPIE Proceedings, 2010The 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, 1970Abstract 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
2020This 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, 1982Olivine, 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.

Phase Transformation Crystallography of Lath Martensite
MRS Proceedings, 2006AbstractOur current understanding of martensitic transformations has been based on the Phenomenological Theory of Martensite Crystallography developed in the 1950s. Recently, a Topological Model of martensitic transformations has been presented wherein the habit plane is a semi-coherent structure, and the transformation mechanism is shown explicitly to

Martensitic Phase Transformations
1983AbstractThis chapter concentrates on very low-temperature martensitic transformations, which are of great concern for cryogenic applications and research. The principal transformation characteristics are reviewed and then elaborated. The material classes or alloy systems that exhibit martensitic transformations at very low temperatures are discussed ...

The martensitic transformation and the mechanical condition of phases
Metal Science and Heat Treatment, 19751. The cessation of the martensitic transformation in steel and the resumption of the transformation at lower temperatures depend on the change in the mechanical condition of the original phase (austenite) with a simultaneous change in the value of the thermodynamic stimulus of the transformation \3- the difference in free energies \gDFAM.

Martensitic Transformations in β Phase Alloys
1975CsCl type ordered phases occur frequently in equiatomic alloys. Two broad classes of these phases are recognized (1). The first, with by far the largest number of members, involves transition metals in which one component lies to the left and the other to the right of the chromium group.
