Abstract
A theory of surface effects at stepped surfaces in binary ordering alloys is presented. The model is based on pairwise interactions between nearest neighbors and includes long- and short-range-order effects. An example of the [120] stepped surface with [] monoatomic steps and terraces on the [110] plane of a body-centered-cubic alloy is presented. Results for the concentration at all the different sites on the stepped surface as well as for the short-range order parameters as functions of temperature are presented.
