More about PanCobalt database

PanCobalt – Thermodynamic database (TH), Mobility database (MB), and Molar volume (MV) database for multi-component Cobalt-based alloys.

  • The PanCo_TH thermodynamic database consists of 20 components, 379 phases, and 187 assessed binary and 90 assessed ternary systems. The database is validated by published phase equilibrium data.
  • The PanCo_MB mobility database assessed mobility model parameters for the Liquid, Bcc, Fcc, and Hcp solution phases. It is compatible with PanCo_TH and suitable for the simulation of diffusion controlled phenomena of multi-component cobalt alloys.
  • The PanCo_TP thermophysical property database includes the molar volume database covers all the 379 phases assessed in the PanCo_TH, the surface tension and viscosity properties for the liquid phase. It can be combined with the thermodynamic database for the simulation of thermo-physical properties of Co-based alloys, such as density, thermal expansion, and solidification shrinkage.
