SGSOL - The SGTE Solution Database for use with
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 are:
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, Mg, Mn, Mo, N, Na, Nb, Nd, Ni, Np, O, Os, P, Pa, Pb, Pd,
Pr, Pt, Pu, Rb, Re, Rh, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Ta, Tb, Te, Th,
Ti, Tl, Tm, U, V, W, Tb, Zn, Zr.
Between these elements, there are assessed data
for over 440 binary and higher-order combinations. For example, taking
aluminium alone, there are data for liquid, solid-solution and
stoichiometric phases in the following systems:
Al-Ag, Al-As, Al-Au, Al-B, Al-Bi, Al-C,
Al-Ca, Al-Ce, Al-Cr, Al-Cu, Al-Fe, Al-Ga, Al-Ge, Al-Hg, Al-In, Al-La,
Al-Li, Al-Mg, Al-Mn, Al-Mo, Al-N, Al-Nb, Al-Nd, Al-Ni, Al-P, Al-Pb,
Al-Ru, Al-Sb, Al-Si, Al-Sn, Al-Ta, Al-Ti, Al-V, Al-W, Al-Y, Al-Zn,
Al-Zr, Al-C-Si, Al-Ca-Si, Al-Cu-Li, Al-Cu-Mg, Al-Cu-Si, Al-Fe-Mn,
Al-Fe-Si, Al-Ga-In, Al-Ga-Sn, Al-Mg-Mn, Al-Mg-Si, Al-Mg-Zn, Al-Mn-Si,

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
- expressions for the
excess Gibbs energy for any solution phases formed between the
end-member species. These expressions are derived from various
