More about PanNi database

PanNickel – Thermodynamic database (TH), Mobility database (MB), and Thermophysical property (TP) database for multi-component nickel alloys.

  • The PanNi_TH thermodynamic database consists of 27 components, 343 phases and 310 fully assessed binary and ternary systems. The database is validated by many Ni-based superalloys.
  • The PanNi_MB mobility database assessed mobility model parameters for the Liquid, Bcc, Fcc, and Hcp solution phases. It is compatible with PanNi_TH and suitable for the simulation of diffusion controlled phenomena of multi-component nickel alloys.
  • The PanNi_TP thermophysical property database includes the molar volume database covers all the 343 phases assessed in the PanNi_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 Ni-based alloys, such as density, thermal expansion, and solidification shrinkage.

By integrating PanNi_MB and PanNi_MV with PanNi_TH, the combined database can be used to simulate diffusion-controlled phenomena and thermo-physical properties of nickel-based superalloys. The example shows the simulation of particle size evolution of co-precipitation of γ’ and γ”. The lower figure shows an example of calculated critical resolved shear stress for a nickel alloy Nimonic 105 using the strength model developed for nickel-based alloys considering particles of multiple particle size groups with weak/strong pair coupling or bowing mechanisms.
