Phonon instabilities in high-pressure bcc-fcc and the isostructural fcc-fcc phase transitions of Cs [PDF]
Physical Review B, 2000 The phonon instabilities of cesium related to its pressure-induced $\mathrm{bcc}\ensuremath{-}\mathrm{to}\ensuremath{-}{\mathrm{fcc}}^{(1)}\ensuremath{-}\mathrm{to}\ensuremath{-}{\mathrm{fcc}}^{(2)}$ phase transitions are studied using the density-functional perturbation theory.

Mechanism of the fcc-to-hcp phase transformation in solid Ar [PDF]
The Journal of Chemical Physics, 2017 We present an atomistic description of the fcc-to-hcp transformation mechanism in solid argon (Ar) obtained from transition path sampling molecular dynamics simulation. The phase transition pathways collected during the sampling for an 8000-particle system reveal three transition types according to the lattice deformation and relaxation details. In all

Temperature induced phase transformation in Co
Scientific Reports, 2022 Temperature dependent phase transformation behavior in cobalt from hexagonal close-packed (hcp) to face centered cubic (fcc) has been found to be contradictory to that reported earlier.

Eutectic Reaction and Microstructure Stability in CoCrFeNiNbx High-Entropy Alloys
Metals, 2022 Seven arc-melted and then annealed CoCrFeNiNbx (x = 0.3–0.6) alloys are experimentally and thermodynamically investigated in the present work. All the as-cast and 1000 °C annealed CoCrFeNiNbx alloys are composed of face-centered cubic (FCC) and C14 Laves

The distorted-fcc phase of samarium
Journal of Physics: Conference Series, 2014 Angle-dispersive x-ray powder diffraction experiments were performed on samarium metal up to 50 GPa. We report that the high-pressure distorted-fcc phase has the same hR24 structure observed in praseodymium, but, unlike praseodymium, samarium does not undergo a transition to a second distorted-fcc phase.
