摘要
提出Ｃｏ－Ｃｕ系Ｆ．Ｃ．Ｃ固溶体的不规则溶液自由焓的热力学模型，利用巳知的固溶体溶解度的数据，求出该系Ｐ．Ｃ．Ｃ固溶体的剩余自由焓的参数，其中在温度１３００Ｋ的剩余自由焓计算值与美国的“二元合金热力学性质精选数据”中的实验值很接近。本文还计算出该Ｆ．Ｃ．Ｃ固溶体的临界温度和临界成分以及相应的调幅分解区的边界线．
Giving a thermodynamic model of the flee enrsy of the irregular Solution and USing the dareof the F. C. C Solid Solution Solubility on Co-Cu system,the paper Calculated the thermodynamicperarneters of the excess free energy of the F. C. C Solid Solution. The Calulated data about theexcess free energy of the F. C. C Solid Solution at 1 300k were fuund to be very close to the experimental data in the American handbookl)Selected Values of the Thermodynamic Properties of Binary Alloys. 'The paPCr also Calculated the critical temperature and the crutical comPOSition ofthe F. C. C solid solution as well as the boundary of the Spinalal decomposition area.
