Al-Ba (Aluminum-Barium) R.P. Elliott and F.A. Shunk The assessed Al-Ba phase diagram is based on review of the work of [34Alb], [ 52Fla], [53Iid], and [75Bru]. The compound in equilibrium with Al-rich alloys is Al4Ba; [53Iid] reported the melting point of Al4Ba to be 1097 C. The Al- Al4Ba eutectic is at 651 C and 0.42 at.% Ba. No solubility of Ba in solid (Al) has been reported. The Ba-rich eutectic occurs at 72.0 at.% Ba and 528 C. [52Iid] reported that 5.4 at.% Al was soluble in solid Ba at the eutectic temperature. Al2Ba and AlBa form by peritectic reactions. 34Alb: E. Alberti, Z. Metallkd., 26, 6-9 (1934). 52Fla: E.M. Flanigen, unpublished thesis, Syracuse University, Syracuse, NY ( 1952). 53Iid: M. Iida, Nippon Kinzoku Gakkaishi, 17, 632-634 (1953). 75Bru: G. Bruzzone and F. Merlo, J. Less-Common Met., 39, 1-6 (1975). Published in Bull. Alloy Phase Diagrams, 2(3), Dec 1981. Complete evaluation contains 4 figures, 1 table, and 12 references. 1
