Abstract

The enthalpies of mixing in binary liquid alloys of lutetium with chromium, cobalt, nickel and copper were determined at 1 773 – 1 947 K by isoperibolic calorimetry. The enthalpies of mixing in the Lu–Cr melts (measured up to 40 at.% Cr) demonstrate endothermic effects (ΔH = 6.88 ± 0.66 kJ · mol⁻¹ at x_Lu = 0.60), whereas significant exothermic enthalpies of mixing have been established within a wide composition region for the Co–Lu, Ni–Lu and Cu–Lu liquid alloys. Minimum values of the integral enthalpy of mixing are as follows: ΔH_min = −23.57 ± 1.41 kJ · mol⁻¹ at x_Lu = 0.38 for the Co–Lu system; ΔH_min = −48.65 ± 2.83 kJ · mol⁻¹ at x_Lu = 0.40 for the Ni–Lu system; ΔH_min = −24.63 ± 1.52 kJ · mol⁻¹ at x_Lu = 0.37 for the Cu–Lu system.
