Cd-Cu (Cadmium-Copper) P.R. Subramanian and D.E. Laughlin The assessed Cu-Cd phase diagram is based primarily on the experimental work of [24Jen] and closely follows the assessment of [Hansen]. However, modifications have been made in the (Cu) boundary as well as in the e phase field to bring the phase diagram into accord with more recent experimental studies [47Rau, 62Sul, 81Gla]. The equilibrium phases are (1) the liquid, L; (2) the fcc A1 terminal solid solution, (Cu), with a retrograde solubility of Cd, and a maximum solubility of 2.56 at.% Cd at 650 C; (3) the C36 MgNi2-type hexagonal intermediate phase, b or Cu2Cd, with negligible homogeneity range, which forms peritectically at 549 C; (4) the complex cubic g phase or Cu4Cd3, which forms peritectically at 547 C, with a maximum homogeneity range of ~5 at.% Cd; (5) the complex cubic d phase or Cu5Cd8, which forms congruently from the liquid at 563 C, with a maximum homogeneity range between 52.2 and 66 at.% Cd; (6) the D811 Al5Co2- type e phase or Cu3Cd10, which forms peritectically at 397 C, with a maximum homogeneity range of ~1.3 at.% Cd; and (7) the cph A3 Cd terminal solid solution, (Cd), with a solubility of ~0.12 at.% Cu at 300 C. 24Jen: C.H.M.
