GTT at ASK 2018

The 32nd “Aachener Stahlkolloquium“ (Aachen Steel Colloquium) has just started. This year’s topic is “Metallurgy in Transition 4.0” and the topics include digitalization, biofuels and hydrogen, big data and casting. It is clear that these aim at society’s needs for sustainability and low CO2-emissions while making sure that steel can still be produced in high-wage …

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 …

Why did we name the blog “Equilibrium of Things”?

equilibrium of things

Today, a lot of attention is directed to the Internet of Things, Industry 4.0 and the Digital Twin. These buzzwords describe interesting concepts for our everyday life and for the control of processes in industries. But when you want to connect them with material that changes its state, things become really complicated.

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 …

Why does GTT start a blog?

“In this house, we obey the laws of thermodynamics!” – Homer Simpson.   We at GTT completely agree: The laws of thermodynamics are the solid foundation on which we can build understanding of materials and processes. Not all materials and processes are in equilibrium, but there are also many options to calculate constrained equilibria and …
