1. Molar Volume Database of
Nb-Alloys
PanNb2020_MV is a molar volume database for Nb-based alloys, which is
compatible with the PanNb2020_TH thermodynamic database and suitable for
the simulation of thermophysical properties of Nb-based alloys, such as
density, thermal expansion, solidification shrinkage etc.

1.2 Phases
The current molar volume database covers all 131 phases assessed in the
PanNb2020_TH database.
1.3 Database Validation
The simulated density changes vs. temperature of a series of Nb-based alloys
are shown below to validate the current PanNb2020_MV database.
