Nb-Ta (Niobium-Tantalum) R. Krishnan, S.P. Garg, and N. Krishnamurthy The assessed Nb-Ta phase diagram shows complete miscibility of Ta and Nb in the solid state [46Buc]. The phase diagram constructed by [58Wil], which showed an unbroken series of solid solutions with no evidence of a solid-state transformation in any of the alloys, confirmed that of [57Rog] with a statement that the solidus and liquidus are separated by a maximum of 10 C. The calculated diagram is quite similar to the one experimentally determined by [58Wil], but it presents more reliable solidus and liquidus values. 46Buc: H. Buckle, Metallforsch., 1, 53-56 (1946). 57Rog: B.A. Rogers, U.S. At. Energy Comm., ISC-835, 25-26 (1957). 58Wil: D.E. Williams and W.H. Pechin, Trans. ASM, 50, 1081-1089 (1958). Published in J. Alloy Phase Diagrams, 3(1), Feb 1982. Complete evaluation contains 2 figures, 1 table, and 7 references. 1
