| Abstract: | The standard enthalpies of formation of 18 congruently melting, intermetallic compounds in the (Gd, Ho, Lu)-(Cu, Ag, Au) binary
systems have been determined by high-temperature direct synthesis calorimetry at 1473±2 K. The liquid-liquid enthalpies of
mixing for many of the same alloys have also been obtained in the course of these measurements. The results obtained for the
solid alloys are compared with values calculated from Miedema’s semiempirical model. |
