SGSOL - The SGTE Solution Database for use with MTDATA
The SGTE Solution Database is
developed and maintained by SGTE, a consortium of centres engaged in
the development of thermodynamic databanks for inorganic and
metallurgical systems and their application to practical
problems. It is a general purpose database for use with MTDATA for the calculation
of phase equilibria and thermodynamic properties for a wide range of alloy systems. The database
is particularly strong for steels, aluminium alloys and 3-5 semiconductor systems and contains good
coverage of binary data for low melting point systems, eg solders.
The SGTE Solution Database contains data for
multicomponent, non-ideal solution phases.
Elements included in the current version (4.3) of the database
Ag, Al, Am, As, Au, B, Ba, Be, Bi, C, Ca, Cd, Ce, Co, Cr, Cs,
Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, In, Ir, K, La, Li, Lu,

phases in the following systems:

The database comprises:
- expression for the Gibbs energy (relative to the weighted sum of the enthalpies of the constituent
elements) of the end-member species as a function of temperature.
- expressions for the excess Gibbs energy for any solution phases formed between the end-member
species. These expressions are derived from various thermodynamic models.
