Welcome to GTT

"The 20th century was the century of experiments in materials engineering. The 21st century will be the century of modelling."
GTT-Technologies has specialized for decades in collecting the fruits of experimental work in the form of Gibbs energy databases and in the software that is needed to make use of them - both in the form of user-friendly software dedicated to the analysis of complex equilibria and programming libraries that can be easily integrated into Integrated Computational Materials Engineering (ICME) approaches.
The employed methodology for data evaluation (CalPhad) has led to comprehensive, combinable databases that can be used for various applications.
Using our software and databases will allow you to design new materials and processes, direct an experimental programme, analyse pilot plant or production data and direct process changes and optimize yields. In short: it will allow you to save time and money!
Have a look at our software, the data and our consulting abilities. Use our newsletter to keep up to date with GTT-Technologies and contact us in case of questions!


Congratulations to Dr. Michael Auinger from Warwick University! He has received the T.P. Hoar Award 2016 from the British Institute of Corrosion for his paper “Grain boundary oxidation in iron-based alloys, investigated by 18O enriched water vapour – The effect of mixed oxides in... Read More

The editor of Edge.org, John Brockman, asks one question to the world's leading thinkers. This year it is "What scientific term or concept ought to be more widely known?" and - surprisingly or not - if you search for "thermodynamic" on the page, you will get 16... Read More

Our papers on the thermodynamic assessment of the Ca–Cr–Cu–Fe–Mg–Mn–S system have been published. This system allows two different modelling applications: First it is the basis for Copper metallurgy and second it is needed for preventing inclusions of sulfides from slags, e.g. to avoid nozzle clogging in steel metallurgy. If you are interested in more information,... Read More
