Interest in the L1{sub 2} phase, in the Ti-Al-Cr ternary system, continues due to the search for enhanced mechanical properties in light weight materials for possible structural applications. Additionally, recent work has indicated that alloys based in part on this phase may find use as protective alumina-forming coatings for {gamma}-based titanium-aluminides. In order to aid in the development of structural materials and coatings, the actual phase equilibria must be determined so that the correct processing schemes may be designed. Towards this end, the present work seeks to clarify some of the confusion pertaining to the phase equilibria of the L1{sub 2} phase.
