Since the pioneering prediction of surface melting by Michael Faraday, it has been widely accepted that thin water layers, called quasi-liquid layers (QLLs), homogeneously and completely wet ice surfaces. Contrary to this conventional wisdom, here we both theoretically and experimentally demonstrate that QLLs have more than two wetting states and that there is a first-order wetting transition b...

A study of the development of deformation and transient and residual stresses during quenching in aluminum alloy W319 is presented. Rapid tension tests were performed on W319 in the supersaturated solution state at several temperatures and strain rates. A material model following the mechanical threshold stress (MTS)–Voce formulation is developed and implemented in both a simple one-dimensional...

Changes in the concentration of interstitial iron in multicrystalline silicon wafers after high temperature annealing (900oC) have been monitored by carrier lifetime measurements. Two cooling rates were investigated. The first was considered ‘fast’, meaning the interstitial Fe had no time to diffuse to precipitation sites, and should therefore be frozen-in, despite being far above the solubilit...

By quenching the strength of interactions in a partially condensed Bose gas, we create a "supersaturated" vapor which has more thermal atoms than it can contain in equilibrium. Subsequently, the number of condensed atoms (N(0)) grows even though the temperature (T) rises and the total atom number decays. We show that the nonequilibrium evolution of the system is isoenergetic and, for small init...

We present a detailed investigation on the formation of supersaturated GaAs using Ti + implantation followed by nanosecond Pulsed Laser Melting (PLM). have synthesized high-crystal quality layers with concentrations above insulator to metal transition (Mott limit). The Ti-implanted concentration depth profiles after PLM obtained Time-of-Flight Secondary Ion Mass Spectroscopy (ToF-SIMS) show red...

We present here a simple model describing coexistence of solid and vapour phases. The two phases are separated by an interface. We show that when the concentration of supersaturated vapour reaches the dew-point, the droplet of solid is created spontaneously on the interface, adding to it a monolayer of a “visible” size.

The redistribution of carbon after tempering of a novel nanocrystalline bainitic steel consisting of a mixture of supersaturated ferrite and retained austenite has been analyzed by atom probe tomography. No direct evidence supporting the additional carbon enrichment of austenite beyond that initially achieved during the bainite heat treatment was obtained during subsequent tempering of this hig...

The work considers the thermodynamics and kinetics of initial decomposition stages in a supersaturated binary solid solution inthe framework modified nucleation theory. specific surface energy is considered as function intensive state parameters both cluster matrix, which allows one to uniformly describe clusters critical, subcritical, supercritical size. analysis was performed two stages. On f...

A general method for constructing E(fNOD)-optimal mixed-level supersaturated designs possessing the equal occurrence property is introduced. The method, which gives promising results, is based on new techniques for the construction of supplementary difference sets. AMS (2000) subject classification. Primary 62K10, 62K15; secondary 05B20.
