Enthalpies of mixing in ternary Al–Gd–Mn liquid alloys

Michael Ivanov, Natalia Usenko and Natalia Kotova

Abstract

The enthalpies of mixing in liquid alloys of the ternary Al–Gd–Mn system were determined over a wide range of compositions by means of isoperibolic calorimetry at 1650 K. The measurements of the partial enthalpies of components were performed along five sections: for the ΔAl (sections with xGd/xMn = 0.30/0.70 and 0.65/0.35 for x Al changed from 0 up to 0.30); for the ΔGd (xAl/xMn = 0.80/ 0.20 and 0.50/0.50 for xGd changed from 0 up to 0.30); for the ΔMn (xAl/xGd = 0.29/0.71 for xMn changed from 0 up to 0.26). The enthalpies of mixing in the ternary system were found to be exothermic and steadily increasing in absolute values from the Mn corner towards the Al–Gd constituent binary system, reaching the minimum value of approximately – 37 kJ · mol–1 in the vicinity of the Al0.6Gd0.4 composition, evidently related to the formation of stable Al2Gd phase.
