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
Gourav Mundhra is a joint PhD student in the Department of Metallurgical and Materials Engineering at the Indian Institute of Technology Madras and the Department of Materials Science and Engineering at the National Tsing Hua University. He resides in India and is the lead author of the article “Design of a novel Al–Ti–Zr light-weight alloy: CALPHAD and experiments” which was recently published in the Journal of Alloys and Compounds by Elsevier.
This new professorship is an exciting opportunity for the application of CALPHAD tools and principles, as well as the systems design approach to materials, to be better understood by scientific and engineering communities who may not be fully aware of these concepts yet. Olson’s unique set of skills, which include being an inventor, entrepreneur, educator, engineer, musician and scientist, all contributed to him being named the first Thermo-Calc Professor of the Practice, the practice being that of materials design, where one uses computational tools to design and develop new alloys and materials processes.Continue reading
Thermo-Calc Software have been invited to take part in the European Materials Modelling Council (EMMC) International Workshop 2019 this February in Vienna, Austria. The invitation-only workshop will bring together approximately 150 experts in materials modelling to discuss the progress in the industrial deployment of materials modelling software and, according to the EMMC website, “contribute in setting a common direction among stakeholders in all areas of Materials Modelling.” Continue reading
PhD students, post-docs and scientists working in thermodynamics and interested in learning about or expanding their skills in computational thermodynamics are invited to register for the School for Advanced Thermodynamic Assessments (SATA) arranged by CEA this summer in Presqu’ile de Giens, France.

CALPHAD has a long and storied history that is often overlooked in the larger context of materials science. However, with the signing of the Materials Genome Initiative (MGI) by President Obama in 2011, the large-scale initiatives in the EU around Integrated Computational Materials Engineering (ICME) and similar efforts starting in Asia, with Japan and China in the lead, CALPHAD has been getting more recognition within the Materials Genome community.
This was highlighted in a fascinating presentation given by Dr. Qing Chen of Thermo-Calc Software at the IFAM 2016 conference in Nanjing, China, this September. The presentation discussed the history of CALPHAD and underscored its importance in the larger context of computational materials engineering.
