Pressure induced amorphization of materials

SM Sharma, SK Sikka - Progress in materials science, 1996 - Elsevier
Amorphous phases* of materials are characterized by the lack of translational or
orientational long range order. Although one might expect that the excess entropy due to …

On amorphization as a deformation mechanism under high stresses

H Idrissi, P Carrez, P Cordier - Current Opinion in Solid State and Materials …, 2022 - Elsevier
In this paper we review the work related to amorphization under mechanical stress. Beyond
pressure, we highlight the role of deviatoric or shear stresses. We show that the most recent …

Petrology, elasticity, and composition of the mantle transition zone

J Ita, L Stixrude - Journal of Geophysical Research: Solid Earth, 1992 - Wiley Online Library
We compare the predictions of compositional models of the mantle transition zone to
observed seismic properties by constructing phase diagrams in the MgO‐FeO‐CaO‐Al2O3 …

Electronic transitions in perovskite: Possible nonconvecting layers in the lower mantle

[图书][B] Effects of explosions on materials: modification and synthesis under high-pressure shock compression

SS Batsanov - 1994 - books.google.com
In the 1950s explosives began to be used to generate ultrahigh pressures in condensed
substances in order to modify their properties and structure. Notwithstanding the short …

Thermodynamics of silicate melts: configurational properties

P Richet, DR Neuville - Thermodynamic data: systematics and estimation, 1992 - Springer
The ease with which a liquid adjusts to the shape of its container is a well-known
consequence of the hallmark of the molten state, atomic mobility. Atomic mobility is the very …

Pressure effects on silicate melt structure and properties

GH Wolf, PF McMillan - Reviews in Mineralogy, 1995 - degruyter.com
The high-pressure properties of silicate melts are likely to have played the single most
important role in shaping the physical and chemical evolution of the earth and other …
