Calphad-computer coupling of phase diagrams and thermochemistry vol:18 issue:1 pages:71-79
Phase equilibrium in Nb-Ti-V system is calculated using thermodynamic descriptions of the lower-order systems. The thermodynamic descriptions of Nb-Tl and Nb-V are obtained by optimising available experimental information. The parameters for Ti-V are taken from a recent assessment. Phase diagram of the limiting binaries, liquidus projection, solidus projection, and two isothermal sections are computed.
