In recent years there has been increasing interest in the alloy systems and intermetallic compounds between III and V elements or rare earth and transition metals because of their potential usage as high value functional materials. The understanding of the thermochemical and thermodynamic properties of these alloys would be significant to the related researches. The results obtained in this study are summarized as follows;(1) Heat contents of nine III-V compounds composed of Al, Ga or In and P, As or Sb were determined at 700 - 1250゜C, and the standard free energy changes were derived in relation to temperature.(2) Thermodynamic quantities of the liquid Ga-As and In-As systems were derived based on the heat content-temperature-composition polts for these binary alloys. (3(3) Heat contents of the Cu-Y, La, Ce, Pr and Nd binary systems were determined at 700 - 1100゜C, and the thermochemical properites such as specific heat, heat of fusion and entropy of fusion were derived.(4) hase relations in the Ni-La, Ce, Pr and Nd binary systems and the Ni-La-Ce, Ni-La-Pr or Ni-La-nd ternary systems were determined at 900 - 1250゜C.

近年来，III和V元素或稀土和过渡金属之间的合金体系和金属间化合物因其作为高价值功能材料的潜在用途而受到越来越多的关注。了解这些合金的热化学性质和热力学性质对相关研究具有重要意义。(1)测定了Al、Ga、In和P、As、Sb组成的九种III-V化合物在700-1250゜C温度范围内的热含量，并求出了它们的标准自由能随温度的变化。(3)测定了CuY、La、Ce、Pr和Nd六元系在700-1100゜C的热含量，并求出了比热、熔化热和熔化熵等热化学性质。(4)测定了Ni-La、Ce、Pr和Nd五元系和Ni-La-Ce、Ni-La-Pr或Ni-La-Nd三元系在900-1250゜C的热关系。
