Thermo Physical Properties

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)

Free Energy Of Mixing

Redlich−Kister (R−K) polynomials have been associated with the extended regular associated solution model to predict and explain the thermodynamic properties and structural properties of Al−Fe liquid alloy at 1873 K, 1973 K, 2073 K and  2173 K; 1873 K being its melting temperature. The thermodynamic properties, such as free energy of mixing and activities of free monomers ( and ) and structural properties, such as concentration fluctuation in long wave length limit, chemical short range order parameter and ratio of diffusion coefficients ( have been predicted at above stated temperatures. Renovated Butler model has been employed to predict the surface tension and surface segregation of the alloy at stated temperatures with the help of thermodynamic properties. Theoretical findings prevail that the tendency towards compound formation of the liquid alloy decreases with increase in its temperature beyond melting temperature. Eventually, its surface tension decreases and there is gradual exchange of atoms between the surface and bulk regions to maintain equilibrium at elevated temperatures. The liquid alloy under investigation thus shows ideal behaviours at higher temperatures. BIBECHANA 15 (2018) 60-69
