摘要：

The standard enthalpies of formation of Ni3Ta, Pd3Ta, Pt3Nb, Pt2V and Pt3V have been determined by direct synthesis calorimetry at 1473 +/- 2 K. The following values of DELTAH-f(0) (kJ g-1 atom-1) are reported: Ni3Ta, - (20.4 +/- 2.3); Pd3Ta, -(36.1 +/- 2.0); Pt3Nb, -(46.6 +/- 3.7); Pt2V, -(37.2 +/- 2.5); Pt3V, -(27.4 +/- 3.0). The results are compared with data available in the literature for Ni3Ta and Pt3V and with predicted values from the model of Miedema.
