Tutorial on the Role of Diffusion in Materials

One of Thermo-Calc Software’s most popular tutorials is The Role of Diffusion in Materials. It is a comprehensive tutorial that teaches the user about the role of diffusion in materials and how the Diffusion Module (DICTRA) can be applied to materials design and processing. 


A basic exercise at the beginning of the tutorial walks users through how to assess whether there is any leakage from a tube at a power plant. The exercises get increasingly complex as the tutorial progresses.

This comprehensive tutorial was developed in collaboration with Prof. John Ågren, the original developer of DICTRA, now called the Diffusion Module. The tutorial is designed for engineers interested in using the Diffusion Module (DICTRA), as well as students learning about the role of diffusion in materials. The content in the tutorial ranges from basic diffusion theory all the way to advanced examples of complex diffusion in dispersed structures, so it is useful for people at many levels, from undergraduate studies to someone with a PhD and experience in a related field.

If you use diffusion in your work or are curious about diffusion theory and how Thermo-Calc can be applied to it, this tutorial may be of interest to you. 

The Tutorial Includes:

  • A comprehensive introduction to Diffusion Theory, including when it is important to materials
  • Step-by-step instructions on how to set up and run diffusion simulations in the Diffusion Module (DICTRA), from simple one-phase diffusion problems to complex diffusion in dispersed structures
  • Twelve examples demonstrating the applications of the Diffusion Module (DICTRA) to materials design and processing

The Free Educational Package

Several of the examples in the tutorial can be run using the Free Educational Package available on our website. If you do not have a license for Thermo-Calc, you can use this resource to run some of the examples in the tutorial.
