摘要：

The standard enthalpies of formation of 12 terbium alloys with late transition metals have been determined by direct synthesis calorimetry at 1474+/-2 K. The following values of Delta H-f(0) (kJ g(-1) atom(-1)) are reported: TbNi5, -(27.4+/-0.9); TbRu2, -(23.6+/-1.7); Tb5Ru2, -(29.9+/-1.9); TbRh, -(72.3+/-1.1); TbRh2, -(64.4+/-1.5); TbPd, -(85.2+/-1.6); Tb3Pd4, -(85.5+/-1.4); TbPd3, -(78.8+/-1.5); TbIr2, -(70.6+/-2.6 ); TbPt, -(115.7+/-2.9); TbPt3, -(96.7+/-3.1); TbPt3, -(85.6+/-2.9 ). The results are compared with predicted values from the Miedema model and with available literature data for TbPd and TbPt.
