The segregation tendencies of In-Zn liquid alloys in the bulk and at the surface has been studied at temperatures of 692, 850 and 1000K, using a statistical model based on an association of like-species. The strength of segregation in the bulk of this alloy appear to reduce exponentially with an increase in temperature. The surface tension values between 0.55 and 0.9 bulk atomic fraction of Zn showed an increase with the rise in temperature.
