EFFECT OF MAGNESIUM ADDITION ON THE VACANCY-Mg BINDING FREE ENTHALPY IN Al-Cr ALLOYS

Abstract

The Mg-vacancy binding free enthalpy of Al-Cr solid solution alloys with Mg addition was calculated by electrical resistivity measurements. The obtained value is lower than that obtained for dilute Al-Mg alloys with almost the same Mg content and may be attributed to the diffusion of Mg.
