摘要：

The standard enthalpies of formation of yttrium alloys, Y Me (Me = Ru, Rh, Pd, Os, Ir, Pt) were determined by direct synthesis calorimetry at 1473 +/- 2 K. The following values of DELTAH(f,m)0 are reported (J/mole of atoms) : Ru2Y5, - (27.3 +/- 3.1), RhY, - (76.1 +/- 3.4) ; Rh2Y, - (65.4 +/- 1.3); PdY, - (94.9 +/- 3.8); Pd4Y3, - (92.8 +/- 3.7) ; Pd3Y, - (79.0 +/- 6.5); Os2Y, - (24.8 +/- 2.8); IrY, - (65.9 +/- 3.8); Ir2Y, - (59.4 +/- 2.8); PtY, - (104 +/- 2.3); Pt3Y, - (86.9 +/- 2.0). The results are compared with the predictions of the models, and with earlier data for some of the corresponding zirconium alloys.
