Thermo-Calc User Group Meeting - Lyon 2023

Lyon, France| 23-24 October 2023

We are happy to announce that we will be re-launching the User Group Meeting in Lyon, France, after a long pandemic-induced break. The aim of the meeting is to exchange ideas and experience in the field of CALPHAD-type thermodynamics and kinetics in a relaxed and friendly atmosphere. The meeting will be a two-day event.

The language of all presentations will be English.
