Ag-Be (Silver-Beryllium) H. Okamoto and L.E. Tanner The main features of the assessed Ag-Be phase diagram are adopted from [ Beryllium] and [79Ald]. Only one intermediate phase, d or AgBe2 (Cu2Mg-type), exists in the equilibrium diagram at an off-stoichiometric composition of ~73 at.% Be within a limited temperature range between 1010 and ~760 C. A sizable though not well-defined homogeneity range may exist for this phase. Thermodynamic modeling was found to describe the experimental phase boundaries reasonable well. 79Ald: F. Aldringer and G. Petzow, Beryllium Science and Technology, D. Webster and G.J. London, Ed., 1, 235-305 (1979). Published in Phase Diagrams of Binary Beryllium Alloys, 1987. Complete evaluation contains 3 figures, 6 tables, and 21 references. 1
