Temperature dependence of interaction parameters of Cu–Si liquid alloy

The thermodynamic and structural properties of Cu–Si liquid alloys were computed at different temperatures assuming that the interaction parameters were linearly and exponentially dependent on the temperature in the framework of R–K polynomials. Both these assumptions were found appropriate in explaining the mixing properties of the alloy near the melting temperature. However, the assumption of the linear temperature dependence of interaction parameters could not explain the properties of the alloy when the temperature was elevated. The exponential temperature dependence of the interaction parameters was found successful in explaining the thermodynamic and structural properties of the alloys over a large temperature range.
