On a shock-induced martensitic phase transition

Boundaries for martensitic transition of 7Li under pressure

Physical properties of lithium under extreme pressures continuously reveal unexpected features. These include a sequence of structural transitions to lower symmetry phases, metal-insulator-metal transition, superconductivity with one of the highest elemental transition temperatures, and a maximum followed by a minimum in its melting line. The instability of the bcc structure of lithium is well ...

Nature of an electric-field-induced colloidal martensitic transition.

We study the properties of a solid-solid close-packed to body-centered tetragonal transition in a colloidal suspension via fluorescence confocal laser scanning microscopy, in three dimensions and in real space. This structural transformation is driven by a subtle competition between gravitational and electric dipolar field energy, the latter being systematically varied via an external electric ...

Calculated pressure-induced phase transition in MgF2

Relatively little attention has been paid to pressureinduced phase transitions in the Group II halides in contrast to the volume of work on the Bl-B2 transition in the alkali halides and alkaline-earth oxides. However, recently the rutile to fluorite transition in MgFz has been the subject of a paper by Nga and Ong,’ in which they studied this transition by molecular dynamics simulation based o...

Pressure-induced phase transition in SiC.

The pressure-induced phase transition in silicon carbide is studied using a constant-pressure ab initio technique. The reversible transition between the zinc-blende structure and the rock-salt structure is successfully reproduced through the simulation. The transformation mechanism at the atomistic level is characterized, and it is found that the transition is based on a tetragonal and an ortho...
