Calculation of the free enthalpy of binding of impurity-vacancy in FCC very dilute alloys

A method is developed to obtain values for the free enthalpy of binding of a vacancy to an impurity in very dilute FCC alloys. On the basis of the five-jump frequency model a computer simulation of the diffusion process is carried out using Monte-Carlo methods. This simulation method is then applied to some copper alloys from which experimental values are well known.
