Nickel-based Superalloys Databases

TCNI13 is our thermodynamic and properties database designed for use with different kinds of Ni-based alloys and superalloys. MOBNI6 is the corresponding mobility database needed for use with the add-on kinetic modules.

TCNI13 for Thermodynamic and Properties Data

TCNI13 is a thermodynamic and thermophysical properties database for Ni-based alloys and superalloys. All necessary volume data (including molar volume and thermal expansivity) for various alloy phases is available in TCNI13. TCNI13 also comes with the description of electrical resistivity, thermal conductivity, and elastic constants as well as surface tension and viscosity of the liquid.

The database has been developed in a CALPHAD spirit with all of the constituent binary systems assessed for their full range of composition including all phases, plus most of the Ni-containing ternary systems, and many other ternary systems as well, in order to give an accurate thermodynamic description of the multicomponent systems of interest for various Ni-based alloys and superalloys including, but not limited to:

  • Hastelloy and the Haynes alloys
  • Inconel alloys
  • Waspaloy
  • René alloys
  • Incoloy
  • TMS alloys
  • CMSX single crystal alloys
  • Experimental Co-based superalloys and medium- to high-entropy alloys
  • And more

TCNI13 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.

MOBNI6 for Kinetic Data

MOBNI6 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 would be happy to help you determine whether your work requires a mobility database.

MOBNI6 is compatible and recommended to be used in combination with TCNI13.

Nickel Model Library Free with Purchase of Databases

The Nickel Model Library is a package of property models used to set up calculations in the Property Model Calculator that are common to those working with nickel-based alloys. The library includes five models intended for those working in the nickel industry:  Antiphase Boundary Energy, Coarsening, Equilibrium with Freeze-in Temperature, Solvus for Ordered Phase, and Strain-Age Cracking.

The Nickel Model Library is available for free to all users who have licenses for the nickel databases TCNI (version 11 or newer) and MOBNI (version 5 or newer) and valid Maintenance & Support Subscription (M&SS).

Highlights of the New Release

The new version of our Ni-based Superalloys Database, TCNI13, was released with Thermo-Calc 2025b. Read the Release Notes for more details.

  • Adds elastic constants (C11, C12, C13, C33, and C44) for FCC (A1 & L12), BCC (A2 & B2), 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
    • 1 new binary system (371 total)
    • 2 new ternary systems (433 total)
    • Improves the description of phase equilibria involving σ and/or μ phases in several binary and ternary systems by Effective Bond Energy Formalism (EBEF)
    • Adds viscosity, surface tension, thermal conductivity, and electrical resistivity descriptions for the newly assessed systems

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