Two calorimetric methods: solution and direct reaction techniques were used for determination of the enthalpies of formation of two advanced aluminides: AlNi and AlNi 3 as the main candidates for the high-temperature application. The same comparison

Enthalpies of formation for AlFe were determined by solution calorimetry over a wide concentration range (X Al =0.40–0.50) and over a wide temperature interval (T = 296 to 1029 K). The value of enthalpy of formation becomes more negative with devia
