THERMODYNAMIC ANALYSIS OF BINARY METAL SYSTEMS USING DIFFERENTIAL THERMAL ANALYSIS

摘要

Brief review on history and development of DTA as thermal analysis method; with special aspect to the application of quantitative thermodynaimc analysis for binary metal systems, are presented in this paper. Importance of the calibration constat determination is pointed out, as well as its changeable value depending on composition of the investigated system. Results obtained using DTA method in termodynamic analysis of some binary systems are also given and compared with data measured by other experimental techniques (calorimetry, BMF measurements) or calculated by thermodynamic predicting methods. Good agreement reached between these results enables to the correctness of application of quantitative DTA.
