Crystallographic structure of Ti-6Al-4V, Ti-HP and Ti-CP under high-pressure
(2010-05-11)
The phase stability of a commercial purity (Ti-CP), high purity (Ti-HP) and Ti-6Al-4V alloy were investigated in a diamond anvil cell up to 32 GPa and 298 K using a polychromatic X-ray beam. The Ti-CP and Ti-HP shown the ...

Strength of polycrystalline coarse-grained platinum to 330 GPa and of nanocrystalline platinum to 70 GPa from high-pressure x-ray diffraction data
(AMER INST PHYSICS, 2008-03-15)
X-ray diffraction patterns from platinum foil 300 nm grain size have been recorded up to
330 GPa using a beveled-anvil diamond cell. The compressive strength has been determined from
the analysis of the diffraction ...
Quasiharmonic elastic constants corrected for deviatoric thermal stresses
(AMER PHYSICAL SOC, 2008)
The quasiharmonic approximation (QHA), in its simplest form also called the statically constrained (SC) QHA, has been shown to be a straightforward method to compute thermoelastic properties of crystals. Recently we showed ...
Nonhydrostatic compression of bismuth to 222 GPa: Some constraints on elasticity of the bcc-phase
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)
Polycrystalline bismuth sample was compressed in a diamond anvil cell and X-ray diffraction patterns from the body centered cubic phase of bismuth (bcc-Bi) recorded in the pressure range 12-222 GPa. The analysis of diffraction ...
High-pressure Raman study of graphene: a spectroscopic evidence for the diamondol
(Universidade Federal de Minas GeraisUFMG, 2015-03-30)
In this dissertation, the e ect of high pressures on double transferred CVD graphene sitting on a Teflon substrate were investigated via Raman spectroscopy in a diamond anvil cell (DAC) using water as the pressure transmitting ...
