Materials Specific Databases for use with MTDATA
MTAL - The NPL Aluminium Database
This database is designed to allow calculations of
phase equilibria to be carried out in Al-base alloys. At present the
released version of MTAL (version 5) allows calculations in the 7
and it is being extended incrementally with the
addition of Ti, Ni and Cr.
The database includes pressure dependence of the
Gibbs energy which allows calculations of the density and the effect of
pressure on the phase diagram.
TCFE - The TCAB Database for Steels
This database has been developed by Thermo-Calc
Software AB in conjunction with the CAMPADA project at the Department
of Materials Science and Engineering, KTH. It is based on the TC-FE92
database and includes new assessments carried out up to 1998 for
systems relevant to steels.
The following system is covered:
and it is based on the complete set of critical
assessments of binary and a large number of relevant ternary
assessments with special emphasis on some higher order systems in the
iron rich corner. The database is however eminently suitable for
calculations in the iron rich corner with a Fe minimum of 50wt %. It
has been translated and tested for use with MTDATA.
MTSOLDERS - The NPL Database for Solders
This database is designed for use in the
calculation of phase equilibria involving solders and other low melting
alloy systems. Alloys containing the following elements may be
- Ag, Al, Au, Bi, Cu,
Ge, In, Pb, Sb, Si, Sn, Zn
The database contains critically assessed
thermodynamic data for the 12 elements, all except one (Au-Zn) of the
66 binary systems and five ternary systems (Ag-Cu-Pb, Al-Cu-Si,
Al-Sn-Zn, Au-In-Pb and Bi-In-Pb). The database may be used to make
predictions of liquidus temperatures and phase equilibria in systems
containing these elements but the results are likely to most reliable
close to the binary and ternary systems covered explicitly by the
database. The database is valid for temperatures between
50 °C and 1000 °C.
- Database for Lead Free Solders
This database was created as part of the European
collaborative project COST531.
It is a self-consistent thermodynamic database for lead-free solder
materials and substrates and contains critically assessed thermodynamic
parameters for more than 50 binary systems
collected from the literature or provided directly by a
programme of experimental and assessment work as part of the COST
data were supplemented by parameters for ternary systems to provide a
self-consistent thermodynamic database.The database has been tested
using a variety of proprietary software to ensure its portability.
The database covers the following 11 elements
- Ag, Au, Bi, Cu, In,
Ni, Pb, Pd, Sb, Sn, Zn

for binary phase diagrams
calculated using the solders database. Details about the critical
assessments and calculations carried out using the database have been
published as an Atlas of Phase
Diagrams for Lead-Free Soldering
MTSEMI - The NPL Semiconductor Database
This database contains data for condensed phases
and gaseous species for system: Al-As-Ga-In-P-Sb and will allow
exploration of the conditions appropriate for the formation of the
zincblend phase by chemical vapour deposition processes.
The data have been gleaned from the literature.
The data for the elements are from the SGTE
Unary Database and data for binary condensed phases eg
liquid, zincblend, fcc, rhombo_a7 (94Ans). Data for the ternary systems
are taken from a number of sources; Ga-In-Sb from Yang and Watson
(94Yan), Ga-In-P, Al-As-Ga, Al-Ga-Sb, Al-In-Sb, As-Ga-Sb, As-In-Sb,
As-Ga,P, Ga-P-Sb, As-In-P, In-P-Sb, Al-As-In, As-Ga-P, Ga,P-Sb,
As-In-P, In-P-Sb, Al-Ga-P, Al-In-P, As-Ga-In, Al-As-P, Al-P-Sb,
Al-As-Sb and As-P-Sb (98Zha) and Al-Ga-In (78Ans).
MTFEDLSL - The NPL Dilute Solution Database for Fe
This database contains data for the dilute
solution of 26 elements in liquid iron modified according to the
modified Wagner model. It can be used in conjunction with SGSUB or with
NPLOX to calculate the solubility of trace elements in liquid iron in
equilibrium with a gas phase or a slag.
