Abstract
In this work, a theory is derived for the calculation and analysis of phase diagram of binary alloys composed of constituent elements having the same structure and any proportion. Analytical expression of phase diagram has been derived using the ratio of root mean square fluctuation in atomic positions on the equilibrium lattice positions and the nearest neighbour distance. The theory is based on Lindemann criterion so that the calculated phase diagram provides information on Lindemann melting temperatures and eutectic point of binary alloys. Numerical results for Cs1-xRbx, Cu1-xAux, Cu1-xNix and Cr1-xCsx are found to be in good and reasonable agreement with experiment.
