Pb-Yb (Lead-Ytterbium) A. Palenzona and S. Cirafici The assessed phase diagram for the Pb-Yb system is based on [67Mcm], with minor modifications made in the melting and transformation temperatures for Pb and Yb to agree with the accepted values. The equilibrium phases include (1) the liquid, L; (2) four intermediate phases, Pb3Yb, PbYb, Pb3Yb3, and PbYb2; and (3) three terminal solid solutions, (Pb), (gYb), and (bYb). The solubility of Pb in (Yb) is negligible and can be fixed at 0.18 at.% Pb. The solubility of Yb in (Pb) is estimated to be > 0.15 at.% Yb. 64Kuz: Yu.B. Kuzma, R.V. Skolozdra, and V.Ya.
