DETERMINATION OF LATTICE STABILITY PARAMETERS AND THEIR APPLICATION

A method is proposed for ascertaining the lattice stability parameters, offering an example of 5 binary phase regions in Cu-Ag and Pb-T1 systems, on the basis of a few thermodynamical data and the state function properties. The calculated binary phase boundaries by using these parameters are in good agreement with the experimental results. Thus, the phase equilibrium among the solid solutions with fee structure in Cu-Ag system has been discussed.
