Al (Aluminum) Ternary Alloy Phase Diagrams - ASM Digital Library This article is a compilation of ternary alloy phase diagrams for which aluminum (Al) is the first-named element in the ternary system. The other elements are C, Co, Cr, Cu, Fe, Ga, Li, Mg, Mn, Mo, Nb, Ni, Sb, Si, Ti, U, V and Zn. The diagrams are presented with element compositions in weight percent. PDF Phase Equilibria in Multi-component ?-titanium Aluminides useful to view some of the critical ternary diagrams. Figs.2&3 show the Ti-Al-Cr and Ti-Al-Nb systems. They are quite different in general form but both are characterised by the formation of a ternary B2 phase. Although only observed in ternary systems, the B2 phase is basically an extension of the B2 phase in Ti-Al that is only just metastable.
