Phase change mechanisms in Ge2Sb2Te5
TL;DR: In this article, the phase transition from amorphous to face-centered-cubic polycrystalline Ge2Sb2Te5 thin films is studied and all the kinetic parameters governing the transition have been determined by in situ transmission electron microscopy analysis.

The reversible crystal-quasicrystal transitions in icosahedral Al—Cu—Fe alloys
TL;DR: In this paper, a powder neutron diffraction technique was used to study two types of reversible transitions of the perfect icosahedral phase in Al-Cu-Fe alloys with a restricted temperature range, between 1020 K and 1120 K.

A comparative study of methods used for the prediction of nonisothermal austenite decomposition
Tamás Réti,L. Horváth,Imre Felde +2 more
TL;DR: In this article, different phenomenological procedures applied to the prediction of the progress of nonisothermal austenite transformation are analyzed and compared and practical applications for prediction purposes are tested on the basis of dilatometric experiments.
