Understanding the Metallurgy of High Entropy Alloys

Prof. Gorsse
Stéphane Gorsse, Associate Professor at CNRS, University of Bordeaux, Bordeaux INP, ICMCB

High Entropy Alloys (HEAs) are presently of great research interest in materials science and engineering. With fundamental issues that challenge the proposed models and methods for conventional alloys, it is an expanding field. Stéphane Gorsse, Associate Professor at CNRS, University of Bordeaux, Bordeaux INP, ICMCB, is a material scientist focused on metallurgy. The author of numerous publications and with extensive experience in the field of metallurgy, Prof. Stéphane Gorsse shares his thoughts on this expanding area and computational thermodynamics.

The Various Uses of TCAL7 TCS Al-based Alloy Database

The versatile TCS Al-based Alloy Database (TCAL7) is developed for aluminum-based alloys. It can be applied, but is not limited, to the industrial grades. Essentially a thermodynamic database, it also has thermophysical properties data available for molar volume with thermal expansion coefficients, electrical resistivity and thermal conductivity of all phases, as well as viscosity and surface tension of liquid. Dr. Hai-Lin Chen, Database Developer at Thermo-Calc Software, describes the multiple advantages of TCAL7.

How to Do a CALPHAD Assessment

People often ask how our thermodynamic and properties databases are developed. The databases contain a tremendous amount of information about the properties of materials and they provide the information needed to complete calculations in Thermo-Calc. A lot of work goes into their development by a team of experts who work continually to expand their functionality and ensure they contain the latest and most accurate information.

We put together a video answering this very question that demonstrates just how this process works. Watch the video to learn how we develop our thermodynamic and properties databases.

All of the files shown in the video can be downloaded so that you can follow along and complete your own CALPHAD assessment:

Advantages of Thermo-Calc for the Aerospace Industry Highlighted in “Heat Treat Today”

Consistency in material properties and performance is critical to the aerospace industry. Small variations in material chemistry or process windows can have a large impact on the final part performance. The ability to predict and adjust for these variations can reduce scrap and part re-work. Metallurgists and process engineers responsible for heat treatments must adapt their processes when input variables change.
