Abstract

Partial 1100, 1000, 900 and 700 °C isothermal sections of the Al-Rh-Ru phase diagram were determined. The isostructural binary AlRu and AlRh phases probably form a continuous β-range of the CsCl-type solid solutions. The Al₉Rh₂ and C-Al₅Rh₂ dissolve up to 4.5 and 13 at.% Ru, while Al₁₃Ru₄ and Al₂Ru dissolve up to 14.5 and 8 at.% Rh, respectively. A ternary orthorhombic structure (Pbma, a = 2.34, b = 1.62 and c = 2.00 nm) related to the Al-Rh ε-phases was revealed at the extension of the Al-Rh ε-phase area at compositions up to Al₇₇Rh₁₅Ru₈.
