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
As the third International Workshop on High Entropy Materials was organized by the Department of Materials Science & Engineering in Kanpur India, three weeks ago, Thermo-Calc software and TCHEA databases enjoyed a host of references to the opportunities created by computerized applications. At a vibrant and compelling gathering of great minds, Bhanu Prasad Babburi, Director at Bhanu Scientific Systems and the Thermo-Calc Software agent for India, participated.Continue reading
A paper was recently published as part of the TMS Proceedings 11th International Symposium on High Temperature Metallurgical Processing which describes in detail how Thermo-Calc can be applied to steel making processes for new and existing steel grades using the new Process Metallurgy Module, which was introduced last year in Thermo-Calc 2019b. The paper, titled The application of an effective equilibrium reaction zone model based on CALPHAD thermodynamics to steel making, describes how an expansion to the module, coming this year, incorporates a kinetic model of the steelmaking process based on the concept of effective equilibrium reaction zones (EERZ) and gives a detailed example of how this module can be applied to the entire steelmaking process using a real case from a steel plant in Ontario, Canda.Continue reading
Thermo-Calc 2020a is released in December 2019 and includes eight new and updated databases, Scheil Simulations with Back Diffusion in the Primary Phase, a new general model for Yield Strength and more.Continue reading
Thermo-Calc 2019b was released in June 2019 and introduces a new module for steel and slag processing, the Process Metallurgy Module, three new databases, a completely rewritten part of the calculation engine and more.Continue reading
The launch of a three-year research project across three countries and involving over 10 leading experts will significantly advance the design of titanium aluminide (TiAl) alloys used in the manufacture of lightweight aircraft turbine engine components.
The ADVANCE project—Sophisticated experiments and optimisation to advance an existing CALPHAD database for next generation TiAl alloys—consists of an extensive and ambitious experimental program to generate detailed and accurate phase equilibrium data for a series of homogenous Ti-Al-X alloys of high purity, aiming to resolve existing experimental controversies and to determine missing data points of relevance, and ultimately support modelling activities consisting of assessing and re-optimising individual subsystems and the development of cutting-edge CALPHAD databases for TiAl alloys.
Thermo-Calc 2019a was released in December 2018 and brings many new databases, improved tools for integrating Thermo-Calc into an ICME workflow and the first ever material-specific property model library.
Thermo-Calc 2018b is released in June 2018 and includes the addition of three key features to the TC-Python API and two new thermodynamic databases for metal oxide solutions (TCOX8) and Mg-based alloys (TCMG5).
