چکیده انگلیسی
The binary alloy Ca-Mg with alkaline earth constituents has drawn the attention of some previous workers due to its glass-forming tendency. We present the study of this aspect on the basis of formation of pseudomolecule or chemical complex CaMg2. The partial and total structure factors Sij(k) and S(k) have been computed and studied on this basis. Various thermodynamical properties viz., heat of formation, heat of mixing, entropy of mixing, concentration fluctuation Scc(0) at long wavelength limit and chemical short-range order parameter (CSRO) have also been studied. Further, the Shaw model of pseudopotential has been used to compute the local screened form factor and consequently the electrical resistivity of the alloy. The surface tension of the alloy has also been studied. The results reasonably agree with the experimental data. Useful informations have been obtained regarding the glass forming nature and metallic interactions of this alloy at 1200Â K.
