Dy-W (Dysprosium-Tungsten) A. Pandian, S.V. Nagender Naidu, and P. Rama Rao The assessed phase diagram for the Dy-W system is based on the work of [66Den]. The eutectic in the system is suggested to be at or just below the melting point of Dy. The measured solubility of W in liquid Dy at the melting point of Dy is regarded as the eutectic composition. It is thus suggested that the eutectic temperature and composition are 1412 C and 0.065 at.% W, respectively. According to [61Bae] and [65Ell], no intermetallic compound exists in this system. Further, [61Bae] reported negligible solid solubility for the system. 61Bae: N.C. Baenziger and J.L. Moriarty, Jr., Acta Crystallogr., 14, 948-950 ( 1961). 65Ell: R.P.
