摘要：

The standard enthalpies of formation of scandium alloys, Sc+Me (Me=Fe, Co, Ni, Ru, Rh, Pd, Ir, Pt) were determined by direct synthesis calorimetry at 1473 +/- 2K. The following values of DELTA(f)H(m)-degrees/(kJ g atom-1) are reported: Fe2SC, -(11.2 +/- 1.2); Co2Sc, -(32.5 +/- 2.1); CoSc2, -(26.7 +/- 1.9); Ni2SC, -(43.0 +/- 2.3); NiSc, -(44.7 +/- 2.3); RuSc, -(44.5 +/- 2.2); Rh3SC, -(51.7 +/- 1.4); RhSc, -(94.5 +/- 1.5); PdSc, -(89.3 +/- 2.2); IrSc, -(89.7 +/- 3.0); lr2SC, -(66.3 +/- 1.3); PtSc, -(104.8 +/- 5.4). The results are compared with predicted values, and with earlier data for some of the corresponding yttrium and titanium alloys.
