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:

Applications of Thermo-Calc to Steel Making Processes Described in New Paper

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.

Next Generation TiAl Alloys Advanced by New European Consortium

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.
