Fluorite Phase Transformations under Vacuum

Phase transformations of amorphous semiconductor alloys under high pressures

The paper reviews the results of experimental studies and thermodynamical modelling of metastable T –P diagrams of initially amorphous GaSb–Ge and Zn–Sb alloys which provide a new insight into the problem of pressure-induced amorphization.

A phase-field approach to solid–solid phase transformations via intermediate interfacial phases under stress tensor

Keywords: Phase transformation Phase-field Interfacial phases Internal stresses Intermediate melt Nucleation a b s t r a c t A thermodynamically consistent phase-field (PF) theory for phase transformations (PTs) between three different phases is developed with emphases on the effect of a stress tensor and interface interactions. The phase equilibrium and stability conditions for homogeneous pha...

Electrochemical Phase Transformations

Adiabatic phase transformations in confinement

The phase diagram of small one-component particles has been analyzed under conditions of thermal insulation, i.e., conservation of energy. In large isolated systems the absolute stability belongs to heterogeneous states with phase separation. However, for small particles the global stability analysis shows a considerable extension of the single-phase regions into a two-phase zone of the phase d...
