Structure, thermodynamic, electrical and surface properties of Cu–Mg binary alloy: complex formation model

Abstract

In the present paper, we have studied the alloying behaviour of Cu–Mg alloy on the basis of the formation of chemical complexes near the melting point along with the pseudopotential technique. The former has been used to compute the partial and total structure factors, heat of formation, heat of mixing, entropy of mixing, concentration fluctuation at long wavelength limit S cc(0) and chemical short-range order parameter (CSRO) of the alloy. The results are in reasonably good agreement with experiment. The pseudopotential technique has been used to compute the local screened form factor on the basis of the Shaw model needed for the computation of electrical resistivity of the alloy. The surface tension has also been studied. Useful inferences have been drawn from the computed result.
