Fatigue-Induced HCP-to-FCC Phase Transformation Resulting in Two FCC-Zr Variants in Pure Zirconium. [PDF]
Materials (Basel), 2023 This study utilized transmission electron microscopy (TEM) and on-axis transmission Kikuchi diffraction (TKD) to investigate the fatigue-induced HCP-to-FCC phase transformation in industrial pure zirconium under a stress ratio of R = 0.1. The results show that fatigue damages result from phase deformations during cyclic loadings.

Phase-field-crystal model for fcc ordering [PDF]
Physical Review E, 2010 We develop and analyze a two-mode phase-field-crystal model to describe fcc ordering. The model is formulated by coupling two different sets of crystal density waves corresponding to <111> and <200> reciprocal lattice vectors, which are chosen to form triads so as to produce a simple free- energy landscape with coexistence of crystal and ...

Proposed mechanism of HCP → FCC phase transition in titianium through first principles calculation and experiments [PDF]
Scientific Reports, 2018 By means of first principles calculation and experiments, a detailed mechanism is proposed to include the stages of slip, adjustment, and expansion for the HCP → FCC phase transformation with the prismatic relation of $${{\{}{10}\bar{{1}}{0}{\}}}_{{hcp}}{

First Principles Theory of the hcp-fcc Phase Transition in Cobalt [PDF]
Scientific Reports, 2017 Identifying the forces that drive a phase transition is always challenging. The hcp-fcc phase transition that occurs in cobalt at ~700 K has not yet been fully understood, although early theoretical studies have suggested that magnetism plays a main role

Deformation Behavior of Pure Titanium With a Rare HCP/FCC Boundary: An Atomistic Study [PDF]
Materials Research, 2020 The compressive and tensile behaviors in a Ti nanopillar with a biphasic hexagonal close-packed (HCP) /face-centered cubic (FCC) phase boundary are theoretically researched using classic molecular dynamic simulation. The results indicate that the HCP/FCC

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.
