In this blog post we will see how to interpret the phase activity of a phase which does not form in equilibrium for a given temperature and pressure. For this, we will consider an Al-Cu alloy containing 0.01 mol% Cu at a temperature of 500°C and at a pressure of 1 atm and we will […]

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

Sometime ago a customer asked me how to find out if Ca2SiO4 is included in a certain database. Since the answer to this question can be really useful for customers in general, I decided to write this blog on the subject. We will define a substance with a defined chemical composition as a chemical species.
GTT-Technologies yearly invites users of its software family to join the GTT Users’ Meeting. Because of the CoViD-19 Pandemia, the usual face-to-face meeting will exceptionally not take place this year. Feedback from our customers made clear to us that there is a strong interest in alternative formats of the GTT Users’ Meeting. Therefore, we are

We at GTT are very happy that Klaus Hack was awarded the Hume-Rothery Prize 2020. This prize is awarded every year by the Institute of Materials, Minerals and Mining of the United Kingdom in recognition of distinguished achievements concerned with phase relationships in metallic materials or non-metallic materials of metallurgical interest. Please check https://www.iom3.org/award/hume-rothery-prize.html. Congratulations

To enable academic institutions who rely on the use of FactSage in classroom instruction to students during the coming months, GTT would like to help you make the transition to “distance learning” education easier. If you normally use a FactSage server/client installation at your institute to organize your course that includes hands-on training with FactSage,

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

Mats Hillert has shown [*] that what is called a Phase Diagram is derivable from a projection in a so-called Property Diagram. The (molar) Gibbs Energy as the property is plotted along the z-axis as a function of two other variables x and y. For binary systems, for example, T equals y and the mole
