Abstract

Explicit descriptions of the Mo-Al, Fe-Al and Ni-Al systems have been developed and com-bined with descriptions of seven binary systems developed previously to compute significant numbers of isothermal sections in the Mo-Al-Cr, Ni-Al-Fe, Cr-Ni-Al, Al-Ni-Mo and Ni-Al-Ti systems. Comparison of these calculations with limited experimental data yields good results and provides considerable insight into the stability of the bcc phase in these systems. The computations provide detailed information on tie-line configurations and melting minima in these systems.
