Abstract
The mixing enthalpyΔH m of the liquid system Ni-Zr was measured in the Ni-rich range at 1916 K up tox Zr=0.34 at % and for the first time in the Zr-rich range at 2270 K up tox Ni = 0.54 at %. Using the thermodynamic-dapted power series, a composition- and temperature-dependent description ofΔH m was given. Furthermore, the partial differentiation ofΔH m (x, T) by T yielded the excess heat capacityCp xs(x, T). The existence of chemical short-range order (associate) in the vicinity of Ni7Zr2 and NiZr was shown and was discussed with reference toΔH m(x, T) andCp xs(x, T) ( 1748 to 2270 K). With decreasing temperature, the influence of chemical short-range order tended toward the composition NiZr.
