Title: Critical assessment of Flory’s approach for estimating miscibility gap in binary monotectic systems
Authors: Chaubey, Sanjay
Issue Date: Oct-2009
Publisher: CSIR
Abstract: Flory’s  solution approach, which gives expression for the free energy of mixing of binary alloys whose constituent atoms differ largely in size, has been used to find the required model parameters in terms of which expressions for critical temperature (Tc) and critical composition  (Xc) have been derived. Model parameters are capable of describing the thermodynamic behavior of the liquid phase and are useful in constructing the miscibility gap in binary monotectics. Within the limits fairly good agreement has been observed between theoretically calculated and experimentally observed values of Xc  and Tc  along with the reasonable data for the various thermodynamic functions at the desired temperature in four binary monotectic systems chosen for the present study.
