Effects of the Tahir-Kheli,Intermediate-Temperature Teriis on the Clapp and Moss, High–Temperature Formulation of Short Range Order (Sro) in Li-Mg Alloys

Abstract

ABSTRACTPresent calculations of the Cowley-Warren SRO parameters, using the Rasolt-Taylor-Dagens, first principles pair potential for Li-Mg alloys show that the higher order terms of Tahir-Keli's intermediate-temperature solution of the Ising, spin-1/2 ferromagnet modify the Clapp and Moss, hightemperature solution in a very significant way. The present results are compared to previous calculations and measurements on Li-10 at.% Mg and Li-50 at.%Mg alloys.
