Ru-U (Ruthenium-Uranium) P. Chiotti, V.V. Akhachinskij, I. Ansara, and M.H. Rand The assessed phase diagram for the U-Ru system is based on the work of [68Par]. The compound URu has a composition of 47.2 at.% Ru, melts congruently, and undergoes a polymorphic transformation at 795 C. U3Ru5 is stable from room temperature to 1182 C. The maximum solid solubility of Ru in (gU) is reported to be about 7.5 at.%, but the phase diagram indicates about 4.5 at.%. The maximum solubility in (bU) is 2.0 at.% and in (aU) it is 1.1 at.%. The maximum solubility of U in (Ru) is ~1.3 at.%. 68Par: J.J. Park, J. Res. Nat. Bur. Stand., A72(1), 1 (1968). Published in Bull. Alloy Phase Diagrams, 2(4), Mar 1982. Complete evaluation contains 1 figure, 1 table, and 5 references. 1
