Precipitation Simulation (TC-PRISMA)

Combining the TCS High Entropy Alloys Database (TCHEA) with the compatible , TCS High Entropy Alloy Mobility Database (MOBHEA), the precipitation process can be simulated using the Precipitation Calculator, which is part of the Add-on Precipitation Module (TC-PRISMA) in Thermo‑Calc. This example shows the Precipitation Calculator simulation of L12 precipitation in (NiCoFeCr)94Ti2Al4 FCC HEA matrix, in comparison with experimental information from [2018Zha].
