FactSage

A hands-on example for an equilibrium-module calculation

FactSage contains many modules. The major ones for daily work are Equilib and Phase Diagram. In the Equilib module, global Gibbs energy minimization is used to determine the equilibrium state of a complex chemical system defined by its chemical composition, temperature and pressure. Equilib is easy to use: First, the chemical system has to be defined […]

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
