High Entropy Alloys Databases

TCHEA7 is our thermodynamic and properties database designed for use with High Entropy Alloys (HEAs), also known as Multi-principal Element Alloys (MPEA). MOBHEA3 is the corresponding mobility database needed for use with the add-on kinetic modules.

TCHEA7 for Thermodynamic and Properties Data

TCHEA7 is a thermodynamic and properties database for High Entropy Alloys, commonly known as HEAs. HEAs are a new class of materials consisting of more than one principal element in a multicomponent system.

The coupling of our CALPHAD-based computational tools and databases allows for a high-fidelity calculation of thermodynamic properties and phase equilibria in multicomponent HEAs, thus shedding light on the formation mechanism and thermodynamic and kinetic stability of HEAs. This provides an efficient way to design HEAs for desired materials properties based on the prediction of microstructures through process optimization.

TCHEA7 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.

MOBHEA3 for Kinetic Data

MOBHEA3 is a corresponding mobility database that provides kinetic data for those working with the add-on kinetic modules – the Diffusion Module (DICTRA) and the Precipitation Module (TC-PRISMA) – as well as a few specific calculation types, such as Scheil with back diffusion. If you do not purchase a license for an add-on kinetic module, you most likely do not need a mobility database. One of our technical sales representatives can help you determine whether your work requires a mobility database.

MOBHEA3 is compatible and recommended to be used in combination with TCHEA7.
