摘要
The enthalpies of mixing in binary liquid alloys of manganese with the lanthanides (Nd, Gd, Tb, Dy, Tm and Lu) were determined over a wide range of composition by isoperibolic calorimetry. The heats of mixing in the systems were found to change gradually across the lanthanides row from the Mn-Nd system (Delta H-min = -0.40 +/- 0.26 kJ mol(-1) at x(Nd) = 0.14; Delta H-max = 1.99 +/- 0.65 kJ mol(-1) at x(Nd) = 0.60; T = 1 600 K) to the Mn-Lu system (Delta H-min = -6.76 +/- 0.93 kJ mol(-1) at x(Lu) = 0.40; T = 1 700 K)
