About TC-Python

TC-Python is a Python™ language-based SDK available with Thermo-Calc which allows for easy and flexible coupling of Thermo-Calc calculations with other software programs. It was built in the popular language Python™ to give Thermo-Calc users access to many other programs, such as numerical packages like NumPy, SciPy, and TensorFlow, which can now be used in combination with our calculations. It can also be used from within Jupyter notebooks or comparable interactive Python™ consoles.

Many outstanding open source programs are written in Python, so users who have a license for TC-Python have countless options for coupling with free, high-quality development tools. It is truly a tool for Integrated Computational Materials Engineering (ICME).

TC-Python can also be used to develop custom Property Models for the Property Model Calculator. User developed Property Models allow you to customize Thermo-Calc to meet your modeling needs. 

Designed to Be Easy to Use

The Python language is easier to start with than many other programming languages, for example, Fortran or C, making it a good option even for those unfamiliar with programming languages. TC-Python was designed to be easy to learn and easy to use. For example, it:

  • Uses intelligent code completion to help users more easily navigate through the available classes and methods.
  • Allows users to easily do parallel computations.
  • Takes an object-oriented approach, which makes it easier to reuse information (classes/methods) and more quickly run your calculations when you need to change the compositions.
  • Guides users through the process of setting up the simulation, using good default values when you are unsure of what to use and prompting you to add missing information, for example. This minimizes the occurrence of errors and makes it an easy option even for those who do not have experience working with APIs.
  • Includes many examples with the installation, which can be used to both learn about the use of TC‑Python and as a way to build your own calculation simulation.

Includes Almost All Calculation Types from Thermo-Calc

From TC-Python, users have access to nearly all Thermo-Calc calculations available from within the Thermo-Calc Graphical Mode, as well as the Add-on Modules, and the majority of features available in the classic Console Mode, including:

  • Single equilibrium
  • Phase (map) diagrams
  • Property (step) diagrams
  • Scheil solidification simulations
  • Batch equilibrium - This is similar to single equilibrium calculations, but offers significant performance improvements when calculating a lot of fast single equilibria, which are systems with few or non-complicated phases
  • Property Models - This includes both pre-installed libraries and custom property models built using TC-Python
  • Steel Model Library* - a set of Property Models designed to help experts working in the steel industry
  • Nickel Model Library* - a set of Property Models designed to help experts working with nickels
  • Precipitation simulations** - All of the precipitation calculations available in the Precipitation Module (TC-PRISMA) can be integrated into your own programming workflow with TC-Python.
  • Diffusion simulations** - All of the functionality available with the Diffusion Module (DICTRA) in Graphical Mode, and the majority of the commands available with Console Mode, are implemented for use in TC-Python
  • Process Metallurgy Module calculations*** - for steelmaking and steel refining processes

*Requires a license for the Steel Model Library or Nickel Model Library.

**Users who do not have a Precipitation Module (TC-PRISMA) or Diffusion Module (DICTRA) license can make calculations with up to three elements using the DEMO versions of the Add-on Modules that are included in all Thermo-Calc installations.

***Requires a license for the Process Metallurgy Module. Users who do not have a license for the Process Metallurgy Module can make limited calculations using the OXDEMO database.

Develop Custom Property Models

TC-Python includes a powerful feature called the Property Model Framework, which allows users to develop custom Property Models and seamlessly integrate them into Thermo-Calc. Property Models are predictive models stored in the software and run in the Property Model Calculator that allow users to easily predict and optimize properties of materials. All Property Models are also available in the Graphical User Interface of Thermo-Calc. By developing your own models, users can essentially customize the software to meet your modeling needs. Learn more at the Property Model Calculator page.

Availability

TC-Python is available as an add-on to a Thermo-Calc license. In order to run TC-Python, it is necessary to have Thermo-Calc and at least one thermodynamic and properties database installed. If you are interested in purchasing a license for TC-Python, please contact us to discuss which license is right for you.

UPCOMING WEBINAR

Thermodynamic and Kinetic Simulations on Joining and Additive Manufacturing Processes for an ICME Framework

A particular application of joining technologies is the development of contacts for high-performance thermoelectric generators. A CALPHAD-based ICME approach fits wonderfully to analyze and optimize the needed configuration. This webinar will show how a Thermo-Calc and TC-Python framework can be used to simulate the diffusion-reaction phenomena at the IZ to identify expected bonding layers, thickness and morphology. Additionally, a similar approach including the Precipitation Module (TC-PRISMA) and the Diffusion Module (DICTRA) is used to investigate the precipitation kinetics underlying the complex microstructure observed in Ti2AlNb-based alloys produced by additive manufacturing processes.
