Abstract: From the view of chemical short range order and incomplete random mixing existing in liquid binary alloy, absorbing the rational part of past statistical mechanics, a statistical mechanics model of liquid binary alloy has been proposed. From the model, the expressions of component activity were derived. Some parameters have been investigated, and their calculation formulae were obtained. According to the formulae of calculating coordination number, the coordination numbers of Cu Zr, Fe B, Ni B, Co P, Fe P systems were calculated, and the results agreed well with those in literature and in experiments.
