微机冶金热力学数据库的建立及应用

ESTABLISHMENT OF MICRO-COMPUTER METALLURGY THERMODYNAMICS DATA BASE AND ITS APPLICATION

作者用数据库管理系统dBASE-Ⅲ与高级计算语言FORTRAN及BASIC相结合的方法,在IBM PC/XT微机上,建立了冶全热力学数据库(MMTDB)。该数据库可以方便地进行数据检索。修改。删除和增加等操作及数据库的自动维护。它具有计算体系的热力学性质、自动绘制多金属共存体系的M-X-Y及M_1-M_2-X-Y优势区相图等功能。MMTDB既能以人机对话方式直接使用,也可以由应用程序调用。

MMTDB(Micro-Cornputer Metallurgy Thermodynamics Data Base)based on IBM PC/XT has been set up by combining DBMS dBASE-Ⅲ with FORTRAN and BASIC.Searching,revision,deletion,supplement of data and automatic safe guard of MMTDB can be done easily.The tbermochemical properties of systems can be cal- culated.The predominance area diagrams of multiple metal systems such as M1-M2- X-Y can be calculated and drawn automatically.MMTDB can be used alternatly, i.e.directly or indirectly through application programs.
