Major Changes

Beginning with Thermo-Calc 2023b, the Additive Manufaturing Module is available for purchase as an Add-On product within the software. Users can test the Module using the Materials Library template on the homescreen or with the first three examples included in the software.
Beginning with Thermo-Calc 2019b, the Process Metallurgy Module is available to Thermo-Calc users who have the thermodynamic database TCOX8 or newer plus who currently have a valid Maintenance and Support Subscription. The Process Metallurgy Calculator, which is located within Thermo-Calc, is available to all users for up to 3 components where you can use the OXDEMO database.
Beginning with Thermo-Calc 2016a, the Precipitation Module (TC-PRISMA) is located within Thermo-Calc and is no longer a stand-alone installation.
