Abstract
The standard enthalpies of formation of 13 dysprosium alloys with late transition metals have been determined by direct synthesis calorimetr y at 1474 +/- 2 K. The following values of Delta H-f(o) (kJ (mole atom )(-1)) are reported: DyNi, -(35.2 +/- 1.5); DyNi5, -(27.4 +/- 0.7); Dy Ru2, -(27.3 +/- 0.9); DyRh, -(76.5 +/- 2.0); DyRh2, -(62.3 +/- 0.8); D y7Rh3, -(56.8 +/- 2.2); DyPd, -(83.3 +/- 2.0); Dy3Pd4, -(86.6 +/- 2.1) ; DyPd3, -(76.2 +/- 1.5); DyIr2, -(69.9 +/- 2.1); DyPt, -(109.4 +/- 1. 8); DyPt2, -(98.1 +/- 2.8); and DyPt3, -(82.8 +/- 2.2). The results ar e compared with predicted values from the Mie-dema model and with avai lable literature data for DyNi, DyNi5, DyPd, and DyPt.
