| Summary: | Phase relationships of the ternary Al-Cu-Yb system have been assessed using a
combination of CALPHAD method and first principles calculations. A
self-consistent thermodynamic parameter was established based on the
experimental and theoretical information. Most of the binary intermetallic
phases, except Al3Yb, Al2Yb, Cu2Yb and Cu5Yb, were assumed to be zero
solubility in the ternary system. Based on the experimental data, eight
ternary intermetallic compounds were taken into consideration in this system.
Among them, three were treated as line compounds with large homogeneity
ranges for Al and Cu. The others were treated as stoichiometric compounds.
The calculated phase diagrams were in agreement with available experimental
and theoretical data. |
