AbstractAbstract
[en] Formation enthalpies of liquid and amorphous alloys in the Ni-Zr system are determined by high-temperature calorimetry. Mixing enthalpy of liquid alloys is measured in the concentration range of xZr = 0-0.63 at T = 1873 K. Enthalpies of amorphous alloys formation from pure crystalline elements at 298 K are measured for alloys of the Ni0.67Zr0.33, Ni0.4Zr0.60, and Ni0.33Zr0.67 composition. Average excessive heat capacity of liquid supercooled alloys corresponding in their composition to congruently melting intermetallic compounds NiZr and NiZr2 is estimated

Методом высокотемпературной калориметрии опрелены энтальпии образования жидких и аморфных сплавов в системе Ni-Zr. Энтальпия смешения жидких сплавов измерена в концентрационном интервале xZr = 0-0.63 при T = 1873 K. Энтальпии образования аморфных сплавов из чистых кристаллических элементов при 298 К измерены для сплавов составов Ni0.67Zr0.33, Ni0.4Zr0.60 и Ni0.33Zr0.67. Рассчитана средняя избыточная теплоемкость жидких переохлажденных сплавов, соответствующих составам конгруэнтно плавящихся интерметаллидов NiZr и NiZr2Original Title
