About the TCNB1: TCS Nb-based Alloys Database

TCS Nb-based Alloys Database (TCNB) is a thermodynamic and thermophysical properties database for niobium-based alloys and superalloys. All necessary volume data (including molar volume and thermal expansivity) for various alloy phases is available. It also comes with the description of electrical resistivity and thermal conductivity, as well as surface tension and viscosity of the liquid.

TCNB1 Thermophysical Properties

Niobium-based alloys find applications in various industries due to their unique properties. They are commonly used in aerospace and aviation industries for manufacturing superalloys, which are heat-resistant and can withstand high-stress environments, such as jet engines and gas turbines. Niobium-based alloys are also used in medical implants due to their biocompatibility and corrosion resistance. Additionally, these are used in the production of superconductors for applications like MRI machines and particle accelerators. In the automotive sector, Nb-based alloys are used for lightweighting and improving the strength of structural components.

The thermodynamic TCS Nb-based Alloys Database (TCNB) is available for refractory alloys (Nb-based) that exhibit high melting temperature and low density compared to Ni-superalloys. The database can be used to study the influence of alloying by the addition of elements on various properties.

The database can be used with our entire suite of products: Thermo-Calc, the Add-on Diffusion (DICTRA), Precipitation (TC-PRISMA), and/or Additive Manufacturing Modules, and all available SDKs.

The thermodynamic database is compatible with the corresponding mobility database TCS Nb-based Alloys Mobility Database (MOBNB) 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. The current version of the mobility database is MOBNB1.

It is possible to combine several databases to make calculations using Thermo‑Calc.
