An investigation of the Al-Pd-Ir phase diagram between 50 and 100 at.% Al

Partial 1100, 1000, 900 and 790 degrees C isothermal sections of the Al-Pd-Ir phase diagram were experimentally determined. The Al-Pd epsilon-phase region extends up to 22 at.% Ir, the Al4Pd phase dissolves up to 15.5 at.% Ir and the C-Al2,7Ir phase dissolves up to 15 at.% Pd. The Al9Ir2 and Al28Ir9 phases extend up to 2 and 5 at.% Pd, respectively. Two ternary phases were revealed: cubic C-2 (a = 1.5482(2) nm) and hexagonal C-3 (a= 1.09135(14), c = 1.3418(9) nm). The isostructural binary AlPd and AlIr phases probably form a continuous P-range of the CsCl-type solid solutions at the temperatures investigated. (C) 2006 Elsevier B.V. All rights reserved
