The compositional dependence of thermo-physical properties of Si-Ti liquid alloy has been reassessed using different modeling equations at temperatures 2000 K, 2400 K and 2473 K. The thermodynamic and structural properties of the system have been computed in the frame work of quasi-lattice test. The extent of surface segregation and surface tension of the liquid mixture have been computed using Butler’s equations at afore mentioned temperatures. The results so obtained have been compared with the available literature database. Theoretical investigations shows that the compound forming tendency of the system gradually decreases at elevated temperatures and hence it shows ideal behaviours, as expected. BIBECHANA 17 (2020)

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.
