Aluminium-based Alloys Databases

TCAL11 is our thermodynamic and properties database used for application to different kinds of aluminium-based alloys, including but not limited to, industrial grades. MOBAL8 is the corresponding mobility database needed for use with the add-on kinetic modules.

TCAL11 for Thermodynamic and Properties Data

TCAL11 is a thermodynamic and properties database designed for use with aluminium-based alloys, including but not limited to industrial grades, such as:

  • All industrial wrought aluminium alloys from 1000 series to 7000 series
  • All industrial cast aluminium alloys from 1xx.x to 8xx.x
  • Many of the 8000 and 9xx.x series, including Al-Li, Al-Sc, Al-Sn, Al-Ce and Al-Er based alloys

The database consists of 48 elements, including all major alloying elements and many minor alloying elements. It also includes nearly all stable phases in the assessed systems and most important metastable precipitates observed in industrial alloys.

TCAL11 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.

MOBAL8 for Kinetic Data

MOBAL8 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.

MOBAL8 is compatible and recommended to be used in combination with TCAL11.

Various Uses of TCAL and MOBAL

Our databases are constantly under development. In the presentation, “Modern CALPHAD databases for aluminum alloys and their applications,” Dr. Hai-Lin Chen, the primary developer of the aluminum databases, discusses the development of the TCAL and MOBAL databases and presents several applications.

Highlights of the Latest Release 

The new version of our Al-based Alloy Database, TCAL11, was released with Thermo-Calc 2026b. Read the Release Notes for more details.

  • 4 new binary systems assessed (317 total)
  • 12 new ternary systems assessed (135 total)
  • 1 new quaternary system assessed (15 total)
  • Several phases merged to a total of 723 phases
  • Adds elastic properties for BCC (A2 and B2), FCC (A1 and L12), and HCP (A3) phases
    • The elastic constants description can be used to derive the elastic moduli (bulk modulus, shear modulus, and Young’s modulus) for a single-phase microstructure.
    • Several updates to the thermophysical properties
    • The addition of elastic properties enables the calculation of elastic constants and moduli in aluminium-based alloys.

1. Elastic properties are only available for cubic BCC (A2 and B2), cubic FCC (A1 and L12), and hexagonal HCP (A3) phases.
