Is the segregation-dissolution kinetics driven by a surface local equilibrium ? An answer via the kinetic tight-binding Ising model
1992
We study here the relation between the surface segregation at thermodynamical equilibrium in an alloy AcB1−c and the kinetics of either segregation in the system A-B or dissolution of AB or BA. This is possible within a new kinetic model based on the electronic structure: the kinetic tight-binding Ising model (KTBIM). In particular, the existence of a local equilibrium between the surface and the first underlayer is stressed. Some illustrations are given in the particular case of the W-Re system.
