Thermodynamic database for multi-component Cu-rich alloys
Cu, Cr, Fe, Mn, Ni, Pb, Si, Sn and Zn
Al, B, Bi, C, P, S, Sb, Se, Ti, and Zr
– Thermodynamic database (TH), Mobility database (MB), and Molar volume (MV) database for multi-component copper alloys.
- The MDTCu_TH thermodynamic database consists of 19 components, 330 phases and 135 fully assessed binary systems. The database is validated by large number of copper alloys.
- The MDTCu_MB mobility database includes assessed mobility model parameters for the Liquid, Bcc, Fcc, and Hcp solution phases. It is compatible with the MDTCu_TH and suitable for the simulation of diffusion controlled phenomena of multi-component copper alloys.
- The MDTCu_MV molar volume database covers all the 330 phases assessed in the MDTCu_TH, and can be combined with the thermodynamic database for the simulation of thermo-physical properties of Cu-based alloys, such as density, thermal expansion, and solidification shrinkage.
