摘要：

The Standard enthalpies of formation of 14 neodymium alloys have been determined by direct synthesis calorimetry at 1477 +/- 2 K. The following values of Delta H degrees(f) (kJ/g atom) are reported: NdNi5, -(26.2 +/- 1.1); Nd5Ru2, -(17.2 +/- 1.9); NdRu2, -(18.8 +/- 1.2); Nd5Rh4, -(59.9 +/- 2.5); NdRh, -(64.2 +/- 2.0); NdRh2, -(59.9 +/- 1.1); NdRh3, -(44.4 +/- 1.6); NdPd, -(77.2 +/- 2.7); NdPd3, -(73.3 +/- 2.3); Nd5Ir3, -(59.7 +/- 2.7); NdIr2, -(67.6 +/- 1.5); NdPt, -(104.4 +/- 2.6); NdPt2, -(97.9 +/- 2.4); and NdPt5, -(55.0 +/- 3.1). The results are compared with available literature data for some of the neodymium alloys and with predicted values from the Miedema model.
