What is the difference between Fact Pure Substances and SGPS databases?

difference between FactSage and SGPS on the periodic table

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 […]

Example for a FactSage calculation of a non-equilibrium process

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

Applications of FactSage in the Energy Research

evolution of number of publications of factsage in the energy area

In the scope of a preparation work for a project proposal, a literature research was conducted on the applications of FactSage in the areas of combustion and gasification of fossil and renewable carbon-containing raw materials. The research included not only the important coal- and biomass-based fuels, but also all kinds of carbon-containing industrial and domestic

Casting Case Study: Refractory-melt interactions

Casting with bottom teeming

In the scope of the collaborative research center SFB 761, von Schweinichen(*) experimentally investigated the chemical interactions between a high manganese steel melt and different refractory materials employed in assembling an adequate casting system. Normally, when casting in an open atmosphere, one expects worse results considering cleanliness for a top pouring process (Figure 1) than

Understanding Solidification in Selective Laser Melting

Additive manufacturing is definetely a “hot topic” these days. And it is not only hot because of the extreme temperatures needed for processes like Selective Laser Melting (SLM) of molybdenum alloys! SLM of molybdenum alloys deserves attention because it combines a manufacturing process of the future with a material system that has the potential to

How do I add “Balance” as amount for Fe?

I have just been asked by an experienced FactSage user how to add “Balance” when specifying an alloy composition in FactSage. This is one of the features that is very useful but unkown to many, so we should explain it better! This is why we started the GTT-blog anyway… So, let’s consider the case when
