Abstract

Abstract

The environment and architecture of Metallurgical Thermodynamic Database Application System (METHEDAS) which is implemented on the computer HITACH M-150 are described in this paper.
This special database system consists of the following blocks:
1. a database, having memorized all the thermodynamic data of 2211 kinsd of inorganic substances (including elements) and 399 binary alloy systems;
2. a data management system, being able to provide users with four basic functions, namely Select, Update, Delete, Insert;
3. an application program library, having seven programs available forusers to calculate the thermodynamic qroperties of the chemical equilibrium systems;
4. a monitor system, monitoring and coordinating the activities of METHEDAS,
