“…On the other hand, eqs. (9)(10)(11)(12)(13)(14), in principle, are only applicable to the alloys having weak or moderate heteroatomic interactions, i.e., j i =RTj is small. When j i =RTj is large, the segregation (in the case of a strongly positive i ) or clustering or ordering (in the case of a strongly negative i ) in the liquid alloys will develop, thus, the quantitative agreement between the calculated and experimental results becomes less satisfactory.…”
