Influence of protons on Fe-Mg interdiffusion in olivine
[1] We report the experimental measurement of Fe-Mg interdiffusivity in olivine along the [001] crystallographic direction in a water-saturated environment at pressures of 0.1 to 6 GPa and temperatures between 1373 and 1450 K. The concentration of water-derived protons in olivine was controlled by varying the water fugacity. The oxygen fugacity was set by the Ni-NiO solid state reaction, while ...
متن کاملCollective ionic dynamics in a molten binary alloy
A recent experiment @Phys. Rev. Lett. 80, 2141 ~1998!# showed heavily damped excitations in molten Li4Pb, within kinematic scales well beyond those of hydrodynamic sound. These findings pointed to the presence of short-lived out-of-phase atomic motions as the underlying microscopic phenomenon. A series of computer molecular dynamics studies are performed to investigate the details of the atomic...

متن کاملNanostructurization of Fe-Ni Alloy
Data about an effect of cyclic γ-α-γ martensitic transformations on the structure state of reverted austenite Fe-31.7 wt.% Ni-0.06 wt.% C alloy are presented. The effect of multiple direct γ-α and reverse α-γ martensitic transformations on fragmentation of austenitic grains has been investigated by electron microscopy and X-ray diffraction methods. An ultrafine structure has been formed by nano...
متن کاملTransmission electron microscopy study on Co/Fe interdiffusion in SmCo5/Fe and Sm2Co7/Fe/Sm2Co7 thin films
We demonstrate a sharp composition transition at the interface of an as-deposited SmCo5/Fe bilayer, while annealing results in measurable Co/Fe interdiffusion near the boundary. For the annealed SmCo5/Fe bilayer, phase separation occurs within the bcc-layer, forming regions with 3 different Fe:Co ratios. Depositing Fe between Sm-Co layers provides a realistic model for bulk systems. Co/ Fe inte...
