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.
TC-Python is an Application Programming Interface (API) which makes it possible to perform Thermo-Calc calculations from Python™ code. It is developed for a general-purpose next-generation API, and provides state-of-the-art usability for a large number of technical and scientific tasks. Henrik Lasu, MSc, and Dr. Ralf Rettig, both software developers at Thermo-Calc Software, relay the advantages of TC-Python.Continue reading
Thermo-Calc Software are delighted to learn that Prof. Ågren, FASM, Professor Emeritus, KTH Royal Institute of Technology, is named the recipient of the 2021 J. Willard Gibbs Phase Equilibria Award. The Gibbs Award, which recognizes outstanding contributions to the field of phase equilibria, honors Prof. Ågren “For pioneering work in the field of computational thermodynamics and kinetics and their application to materials design and process improvement.”
Thank you to everyone who participated in our Customer Satisfaction Survey for 2020! This year we focused on a general understanding of what you are satisfied with, what we need to improve and which material properties you would like us to develop. We received a lot of useful information, which has been analyzed and is now being integrated into our development roadmaps.
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.
Weiwei Zhang, PhD, Material Scientist at Thermo-Calc Software, was awarded for her paper “Thermodynamic Modeling of the La-Co-O System” (Authors: Weiwei Zhang, Erwin Povoden-Karadeniz, Huixia Xu & Ming Chen). It was recognized as one of six papers in the annual JPED Editors’ Choice Awards. Dr. Zhang’s paper is based on a chapter from her PhD thesis and was edited for publication in the “Journal of Phase Equilibria and Diffusion”.
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:Continue reading
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.
In an article recently published in “Heat Treat Today”, Adam Hope and Paul Mason from Thermo-Calc Software Inc, discuss how modeling and simulation tools such as Thermo-Calc can support engineers in their research.Continue reading
