High-Pressure Equation of State of Molten Anorthite and Diopside
New Hugoniot equation of state data for molten diopside (at 1773 K) and molten anorthite (at 1923 K) are reported to 38 and 35 GPa, respectively. The diopside data (initial density, 2.61 Mg/m s) are described by a straight-line fit to the shock velocity-particle velocity results of Us -3.30 + 1.44 Up km s -1, and our preferred fit to the anorthite data (initial density, 2.55 Mg/m s) is given by...
متن کاملShock compression of liquid silicates to 125 GPa: The anorthite‐diopside join
[1] We determined the equation of state (EOS) of three silicate liquid compositions by shock compression of preheated samples up to 127 GPa. Diopside (Di; Ca2Mg2SiO6) at 1773 K, anorthite (An; CaAl2Si2O8) at 1923 K and the eutectic composition Di64An36 at 1673 K were previously studied by shock compression to 38 GPa. The new data extend the EOS of each composition nearly to the Earth’s core‐man...
متن کاملTensile Creep of Polycrystalline Near-Stoichiometric NiAl
Long term tensile creep studies were conducted on binary NiAl in the temperature range 700-1200 K with the objectives of characterizing and understanding the creep mechanisms. Inverse and normal primary creep curves were observed depending on stress and temperature. It is concluded that the primary creep of NiAl is limited by dislocation mobility. The stress exponent for creep, n, decreased fro...

Creep polycrystalline ice samples antifreeze glycopeptides re-accelerating or tertiary samples. Previous work grain-boundary migration consistent with this, as nucleation and growth of curves containing (AFGPs) creep that has shown obtained from the low concentrations of do not show the is found in pure ice that AFGPs inhibit in ice and the present results are tertiary creep is associated with ...
متن کاملTempera~re-dependent thermal expansivities of silicate melts: The system anorthite-diopside
Ah&act-The tem~ratu~-de~ndent thermal expansivities of melts along the join ano~hite-diopside have been determined on glassy and liquid samples using a combination of calorimetry, dilatometry, and Pt double bob Archimedean densitometry. Supercooled liquid volumes and molar thermal expansivities were determined using scanning calorimetric and dilatometric measurements of properties in the glass ...
