Thermo-Calc 2018a was released in March 2018 and includes an entirely new API, new databases for aluminium and high entropy alloys, major updates to the Precipitation module (TC-PRISMA) and more.
Highlights of the Thermo-Calc 2018a release:
New Python API
Thermo-Calc 2018a includes a new PythonTM API called TC-Python. This new API allows users to couple Thermo-Calc calculations with other software in an open way, making it an integral part of the ICME framework.
The API was built in PythonTM because it is a popular language which gives users access to many other programs, such as numerical packages like NumPy and SciPy, which can now be used in combination with our calculations.
In this release, TC-Python focuses on equilibrium calculations and the Precipitation module (TC-PRISMA), making it the first Thermo-Calc API that allows users to make precipitation calculations. Users who do not have a Precipitation module (TC-PRISMA) license can still make calculations with up to three elements using the DEMO license for the Precipitation module included in your software.
We will continue to expand TC-Python and plan to offer step, map and Scheil calculations, as well as Diffusion calculations in the coming releases.
All users with a current Maintenance and Support Subscription, e.g. those who have Thermo-Calc 2018a, are being offered a free trial license of TC-Python until the end of 2018 so you can test the program and discover how you can integrate it into your overall workflow. To request your free trial license, visit the TC-Python page on our website.

Two New High Entropy Alloys Databases
The 2018a release includes new thermodynamic and kinetic databases for high entropy alloys.
TCHEA3: Six new elements have been added to the thermodynamic high entropy alloys database, bringing it to a 26 element framework (Al, B, C, Co, Cr, Cu, Fe, Hf, Ir, Mn, Mo, N, Nb, Ni, Re, Rh, Ru, Si, Sn, Ta, Ti, V, W, Y, Zn and Zr). This new database also includes more than 100 new binary systems and more than 150 new phases.
MOBHEA1: This is the first kinetic database for high-entropy alloys (HEA) from Thermo-Calc Software. The database is suitable for simulation of diffusion controlled phenomena using the add-on Diffusion Module (DICTRA) and/or the Precipitation Module (TC-PRISMA) and is intended for use with TCHEA3. It can also be used together with all Thermo-Calc programming interfaces. The database consists of 22 elements and 5 phases.
New Aluminium Mobility Database
MOBAL4: This new version of our aluminium mobility database adds the element erbium (Er), bringing it to a 35 element framework. The database includes an improved description of liquid and has many new and updated binaries. It also now includes ternary and quaternary descriptions. The database comprises 3 phases, 37 binary systems, 20 ternary systems and 2 quaternary systems.
Improved Grid Creation for Equilibrium Calculations
This release offers improved convergence for phases with charged species. This improvement makes it easier to do equilibrium step and map calculations for oxides.
Updates to the Precipitation module (TC-PRISMA)
There are two major updates to the Precipitation module (TC-PRISMA) in the 2018a release, as well as several smaller improvements.
Updates to the Diffusion module (DICTRA)
The Diffusion module has two new features, one in the Console Mode and one in the Graphical Mode.
Improvements to Usibility
Thermo-Calc 2018a provides several improvements to usability, including:
Thermo-Calc 2017b was released in October 2017 and includes several new databases, major upgrades to the Diffusion and Precipitation modules and more.
Highlights of the 2017b Release:
TCTI1: This is the first ever CALPHAD thermodynamic database which covers both Titanium-based alloys and Titanium Aluminium-based materials in a single database. The database consists of 23 elements, 236 assessed binary systems and more than 70 assessed titanium containing ternary systems. The database can also be employed to design light alloys based on the Al3Ti and AlTi3 intermetallic phases.
MOBTI2: The second edition of the titanium mobility database is designed specifically to be compatible with TCTI1.
TCNOBL1: A new thermodynamic database for noble and precious metal alloys which consists of 21 elements. The database can be applied to jewellery, decoration industries and dental alloys, as well as delicate components for scientific equipment, such as thermocouples and calorimetry elements.
TCAL5: The aluminium alloys database was expanded to include erbium, bringing it to a 35 element framework. The database includes 258 assessed binary systems and 87 assessed ternary systems. This update highlights the assessment of many binary and ternary systems relevant to the 8xxx and 8xx.x series of industrial aluminium alloys, including but not limited to Al-Ce, Al-Er, Al-Li, Al-Sc and Al-Sn alloys.
TCHEA2: The new version of the high entropy alloys database has improved stability descriptions of the sigma phase.
SSUB6: The SGTE Sustances Database has received general updates.
New Features in the Diffusion Module (DICTRA)
The graphical mode version of DICTRA, known as the Diffusion module, includes several new features that extend the functionality and flexibility of the program and make it more user friendly.
Thermo-Calc 2017b includes 3D plotting for Grid calculations in the Property Model Calculator and the Equilibrium calculator. See example T_11_Coarsening_and_Interfacial_energy or the accompanying T-11 tutorial video.
Improvements to the Scheil calculator
The Scheil Calculator has been updated to be faster and more reliable. The improved Scheil calculator has better handling of multiple composition sets and no longer resets if a new composition set is found. Additionally, it now automatically changes numerical settings if needed.
Thermo-Calc 2017a was released in late March 2017 and includes many significant changes to the software.
Highlights of the 2017a Release:
DICTRA Available in the Graphical Mode
The software program for accurate simulation of diffusion controlled reactions in multicomponent alloy systems formerly known as DICTRA is available in the graphical mode for the first time ever as an add-on module in Thermo-Calc 2017a. The new graphical version, known as the Diffusion module, incorporates much of the functionality of the console mode version of DICTRA with the easy-to-use graphical interface of Thermo-Calc, making it easier than ever for users to begin making diffusion simulations. The new graphical mode comes complete with four examples and a Quick Start Guide to help users begin working in the module immediately. Users without a DICTRA license will be able to test the module using DEMO databases included in their software. Watch the new Diffusion module (DICTRA) examples videos.
User Developed Property Models
A new Property Model Development Framework allows users to develop their own property models and seamlessly integrate them into Thermo-Calc. This new framework vastly expands what users can do with the software by allowing you to customise the software to meet to your industry's needs.
Models are developed using the easy-to-learn programming language Python, and model development is possible without any additional installation using a simple editor, such as Notepad++. Users can also use a Python Integrated Development Environment to access advanced features such as debugging of the property models and autocompletion.
Models are automatically encrypted, for safe and secure file sharing.
Learn more and and get started with the step-by-step model development guide.
New Liquidus and Solidus Model
The Property Model Calculator has a new Liquidus and Solidus model which makes it fast and easy to complete this common calculation. For example, with this model, one can easily use uncertainty calculations, varying one or more conditions and see how that affects the liquidus and solidus temperatures.
Examples accessible from the software
Examples can now be accessed from within the software in the Help menu > Open Examples. The examples files are fully configured and ready to run. Users who do not have a Diffusion module (DICTRA) or Precipitation module (TC-PRISMA) license can run the examples with only two elements using the free DEMO databases included in your software.
PDF Documentation available in the software
Users can now access all documentation in PDF format from within Thermo-Calc in the Help menu > Open Manuals Folder. The Online Help is also still accessible in the Help menu > Online Help. Online Help is is fully searchable and cross-referenced for easy use.
