This challenge has necessitated continual improvement in the capability and reliability of available thermochemical software, in particular, in the robustness of the Gibbs energy minimization routine dealing with the intricate physical and mathematical models now used in calculations of multiphase equilibria in multicomponent systems. It is for these reasons that thermodynamic calculations are now an essential component in the development of many new materials. The demands on time and financial resources would be astronomical. The complexity of the materials required for today’s wide variety of technological applications presents a challenge to the materials developer, which cannot be met by experimentation alone. With the significant advances that have been made over the last 30 to 40 years, computational thermochemistry is now a well-recognized and respected discipline in its own right and many technological advances have been and continue to be made using commercially available calculation software and databases. In the framework of FactSage, the user now has access to one of the world’s most powerful and reliable tools for carrying out calculations to investigate materials problems of all types. Gunnar Eriksson, the author of the Gibbs energy minimization routine at the heart of the FactSage software, has received multiple awards for his work, including the dedication of special issues both of the CALPHAD journal and Zeitschrift für Materialkunde to papers presenting applications of his software. These are located at Ecole Polytechnique, Montreal, Canada, and at RWTH and GTT, Aachen, Germany. Why is FactSage the best choice to support your materials research?įactSage, together with its multiplicity of supporting databases, finds its origins in research carried out over a period of some 40 years in two leading centres in the field of materials thermochemistry.
