The standard enthalpy of formation Delta H-t(m,(298)) for the compound Al0.
28Fe0.72 has been determined with a Tian-Calvet calorimeter (Setaram), by d
issolution in an aluminium bath at 800 degreesC (1073 K). The single-phase
alloy was prepared by levitation melting followed by annealing. The experim
ental value found is Delta H-f(m(298)) = -24 645 +/- 422 J/mol. (C) 2001 El
