Ce-Tb (Cerium-Terbium) K.A. Gschneidner, Jr. and F.W. Calderwood In the Ce-rich fcc region, all lattice parameter data show a positive deviation from Vegard's law. At somewhat higher Tb content where the structure is dcph (from about 25 to 55 at.% Tb), all data show a negative deviation that increases as the Tb content increases. The negative deviation from ideality continues in the d phase region (up to about 70 at.% Tb), but in the cph region (75 at.% Tb and higher) a small positive deviation exists. Editor's note: The Ce-Tb phase diagram was sketched by [Moffatt] based on the information provided above. This updates the evaluation by K.A. Gschneidner, Jr. and F.W. Calderwood published in Bull. Alloy Phase Diagrams, 3(1), Jun 1982, which contains 2 figures and 4 references. 1
