Non-equilibrium growth of a binary alloy

Non-equilibrium fluctuation dissipation relations in binary glasses

We show that at short time aging is realized in a simple model of binary glasses. We find that below the transition point the off-equilibrium correlation functions and response functions are compatible with the relations that were originally derived Cugliandolo Kurchan for generalized spin glasses.

Effect of the vacancy interaction on antiphase domain growth in a two-dimensional binary alloy

We have performed a Monte Carlo simulation of the influence of diffusing vacancies on the antiphase domain growth process in a binary alloy after a quench through an order-disorder transition. The problem has been modeled by means of a Blume-Emery-Griffiths Hamiltonian whose biquadratic coupling parameter K controls the microscopic interactions between vacancies. The asymmetric term L has been ...

Non-equilibrium structure of the vapor-liquid interface of a binary fluid

The evaporation of a binary liquid mixture of monatomic species into near vacuum has been investigated by molecular dynamics simulations. It has been assumed that atomic interaction forces can be derived by Lennard-Jones potentials. Results are presented about surface composition changes induced by evaporation, the shape of the distribution functions of evaporating atoms. Estimates of evaporati...

Existence for a stationary model of binary alloy solidification

— A proof of existence is given for a stationary model of alloy solidification. The System is composed ofheat équation, soluté équation and Navier-Stokes équations. In the latter, Carman-Kozeny penalization of porous medium models the mushy zone. The problem is first regularized and a séquence of regularized solutions is built thanks to Leray-Schauder's fixed point Theorem. A solution is then e...
