PanMolybdenum – Thermodynamic database (TH), Mobility database (MB), and Molar volume (MV) database for multi-component molybdenum alloys.
- The current PanMo_TH thermodynamic database consists of 12 components, 168 phases, and 61 fully assessed binary and ternary systems. It can be used to describe phase equilibrium and thermodynamics of molybdenum-rich alloys.
- The current PanMo_MB mobility database assessed mobility model parameters for the Liquid, Bcc, Fcc, and Hcp solution phases. It is compatible with PanMo_TH and suitable for the simulation of diffusion controlled phenomena of multi-component molybdenum alloys.
- The current PanMo_MV molar volume database covers all the 168 phases assessed in the PanMo_TH, and can be combined with the thermodynamic database for the simulation of thermo-physical properties of molybdenum alloys, such as density and thermal expansion.

Coupling PanMo_TH thermodynamic database with PanMo_MB mobility database, user can simulate diffusion controlled phenomena. By integrating PanMo_TH with PanMo_MV, molar volume, density, thermal expansion, and other properties can be calculated for molybdenum alloys. This is an example which compares the calculated and measured molar volume of Mo-Ti Bcc alloys.
