  Standard enthalpies of formation of scandium alloys, Sc+Me (MeFe, Co, Ni, Ru, Rh, Pd, Ir, Pt), by high-temperature calorimetry

  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.

  As a result of an investigation of the alloys of the Sc-Rh system using metallography, X-ray diffraction, microprobe and differential thermal analysis and melting point determination according to the method of Pirani and Alterthum, the constitutional diagram of the Sc-Rh system has been constructed. Two intermediate phases, Sc2Rh and Sc3Rh, were observed. The existence of three other phases in this system, namely ScRh3 (Cu3Au-type structure), ScRh (CsCl) and Sc3Rh13 (a proper type of structure), has been confirmed. The phases ScRh, Sc3Rh and Sc57Rh13 melt congruently at 1990 degrees C, 1110 degrees C and 1150 degrees C respectively. The phases ScRh3 and Sc2Rh form by peritectic reactions at 1650 degrees C and 1080 degrees C respectively. The phases Sc2Rh and Sc3Rh decompose by the solid state reactions at 980 degrees C and 930 degrees C respectively. The coordinates of four eutectic points and one eutectoid point are determined.
