Structural phase transition of aluminum induced by electronic excitation

The dynamics of a structural phase transition induced by interband electronic excitation in aluminum is studied by determining the time evolution of the dielectric constant at 1.55 eV through the measurement of the transient reflectivity induced by an ultrafast pump pulse. The threshold fluence and the time scale for this transition are significantly less than the values necessary for ultrafast...

A two-phase equation of state for Aluminum

By well-established theoretical means, it is now possible to calculate thermodynamic properties of elemental crystals and liquids to an accuracy matching that of available low-pressure experiments; it is also known that the neglect of anharmonicity and electron-phonon interactions introduces errors smaller than 5% at low pressures. To check this theoretical framework and the validity of these a...

experimental and numerical investigation of groove pressed ufg pure aluminum

fabrication of ultrafine grained materials by imposing severe plastic deformation for improvement of mechanical and physical properties of metals has been the focus of many researches over the past few years. in this process, a sheet is subjected to repetitive shear deformation conditions by utilizing asymmetrically grooved and flat dies through alternate pressing. in this study, a 2mm thick co...

Oxidation State of Fe and Ti Ions Implanted in Yttria-Stabilized Zirconia Studied by XPS

The oxidation state of Fe and Ti ions implanted in yttria stabilized zirconia (YSZ) was studied by XPS (X-ray photoelectron spectroscopy) in combination with depth profiling using Ar + sputtering. In the "as-implanted" state of the sample Fe was found to be present as Fe 3 +, Fe 2+ and as metallic Fe °. This is in agreement with earlier conversion electron Mrssbauer Spectroscopy measurements. F...
