From September 19th to 21th 2022 the International Freiberg Conference on waste gasification (https://freiberg.gasification-freiberg.com/) will take place and we are excited to be there! Waste gasification is an important topic for us at GTT, because it contributes to the rational and efficient usage of natural resources. GTT will be represented by two talks: Talk 1: …

The latest FactSage release, FactSage 8.2, comprises a completely new tool to facilitate the development of thermodynamic databases based on the Calphad methodology – the Calphad Optimizer (Figure 1). Figure 1: The new Calphad Optimizer in FactSage 8.2. The goal of database development is to derive a set of self-consistent thermochemical parameters that allow the …
From September 27th to 29th 2022 the Material Science and Engineering (MSE, https://dgm.de/mse/2022/) conference will take place in Darmstadt and we are excited to be there! In total, GTT will be represented by three talks: Talk 1: Building a common platform for thermodynamic optimizations Speaker: Florian Tang When: 09/28/2022, 9.20 AM CET Talk 2: Accuracy …
In recent years, there has been a continuous societal and industrial effort to promote the so-called „circular economy“. According to this paradigm, for producing engineering materials in general, and metals and alloys in particular, the chemical elements which are presently necessary in our economy should not be extracted from the so-called primary ores but instead …

Prof. In-Ho Jung from Seoul National University, our colleague and FactSage co-developer, gave a FactSage Workshop during the conference MOLTEN 2021. This workshop included self-learning videos which are freely available online via his website: MOLTEN2021-FactSageWorkshop-HTTL The following topics were covered in the workshop: Thermodynamic Database Development Ferrous Pyrometallurgy Alloy Design Macro Processing It is an …
Harvey and Gheribi[1] developed a thermochemistry-based model for the iron blast furnace. In their work, the corresponding process model was developed with a flowsheeting approach based on the connected local equilibrium reactors method, which was implemented using SimuSage, one of the very successful members the GTT’s product family. The model was constructed based on the …

I have just attended the virtual DGM meeting which is concluded by the award presentation. My congratulations go to Katharina Esleben from University of Siegen and her co-authors, who have received the Werner-Köster award for their article Effect of Cr and Ni on the microstructural evolution in Co–Re–Cr–Ni alloys in the International Journal of Materials …
The loss of copper in the converting process through its incorporation to the converter slag represents a major problem in the copper metallurgy. There are two important mechanisms for this phenomenon: the physicochemical and the mechanical one. The mechanical mechanism, i.e. the mechanical entrapment of matte or of metallic copper inside the slag, is by …

I have been asked by a potential customer: “Do I need the Fact Pure Substances or SGTE Pure Substances database?” The answer is: It depends. The two databases are both collections of (normally published) thermochemical data. The Fact Pure Substances database FactPS is maintained by our co-developer of FactSage, Thermfact/CRCT, Polytechnique Montreal. It is generally …

It is a common misconception that thermodynamic calculations can only be used for processes that are in equilibrium. In fact, there is a lot to learn from an Integrated Thermodynamic Databank System like FactSage even if you are far away from equilibrium! As example we consider the popular Fe-C system: If you choose all phases …
