TCTI5 is a thermodynamic and properties database for conventional Ti-based and newly emerging γ-TiAl based alloys. All necessary volume data (including molar volume and thermal expansion) for various solution and intermetallic phases is available in TCTI5.
This database can be used to calculate various phase diagrams and thermodynamic properties in assessed systems, but also to predict stable and metastable phase equilibria (β-transus temperature, evolution of phase fractions vs. temperature, martensitic temperature, and so on) for a wide range of multicomponent alloys of industrial relevance, with light impurities (O, N, H, etc.) taken into account. Ti- and γ-TiAl-based alloys of relevance that can be studied include, but are not limited to:
Alpha and near-alpha alloys, such as Ti-6242Si
Alpha-beta alloys, such as Ti64
Beta or near-beta alloys, such as Ti 10-2-3
γ-TiAl based alloys, such as TNM alloys
TCTI5 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.
MOBTI4 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.
MOBTI4 is compatible and recommended to be used in combination with TCTI5.
