摘要：

The standard enthalpies of formation of eight Pr alloys were determined by direct synthesis calorimetry at 1473 +/- 2 K. The following values of DELTAH(f)-degrees (kJ/g atom) are reported: PrNi5, -(25.6 +/- 1.0); PrRu2, -(16.9 +/- 1.5); PrRh2, -(60.4 +/- 1.7); PrPd, -(78.8 +/- 2.5); PrPd2, -(82.7 +/- 3.1); PrIr2, -(70.7 +/- 2.8); PrPt, -(103.4 +/- 2.7); and PrPt2, -(93.5 +/- 2.4). The results are compared with data from available literature for some of the Pr alloys and with predicted values from the model of Miedema et al.
