Abstract It is shown that a quasi-chemical description of long-range order in Fe rich FeAl alloys requires two independent order parameters and at least second neighbour bonding. Using the zeroth approximation, the defining equations for order are obtained. The transformation temperature consequences of the calculation are employed in evaluating experimental data and a revised version of the FeAl phase diagram is arrived at. It is shown that for compositions greater than 25 at% Al the onset… CONTINUE READING
