N2 - The In-Ir phase diagram was investigated by means of X-ray diffraction, electron probe microanalysis and thermal analysis. The existence of the two intermetallic compounds In3Ir and In2Ir was confirmed, and it was found, that In3Ir transforms into a low-temperature modification In3Ir-LT (CFe3-type structure, oP16, Pnma) at temperatures below about 350 °C. The peritectic decomposition reaction of In3Ir and In2Ir at 981 °C and 1188 °C, resp., was confirmed. There are no indications of a liquid miscibility gap as suggested earlier in the literature. On the other hand, some of the experimental results point to the existence of a metastable high-temperature phase In54Ir46. Enthalpies of mixing were determined by high-temperature drop-calorimetry between 1190 and 1390 °C. The minimum in the extrapolated enthalpy of mixing curve is about -18 kJ mol-1 at a composition slightly above xIr=0.5. Œ 2002 Elsevier Science B.V. All rights reserved.
