چکیده انگلیسی
The Al-Pd-Re phase diagram was studied in the compositional range above 50 at.% Al at temperatures between 700 and 1100 °C. Apart from the Al-Pd É-phases exhibiting ternary extension up to â¼6 at.% Re, the binary phases in both Al-Pd and Al-Re dissolve only a little of the third element. In addition to the stable ternary icosahedral and decagonal phases reported earlier a new ternary hexagonal Ï-phase (a â 1.231, c â 2.742 nm) was discovered in a compositional range from Al77.8Pd13.8Re8.4 to Al76.2Pd19.0Re4.8. The overall compositional range of the icosahedral phase was found to be between 8.3 and 10.4 at.% Re and between 68.5 and 71.9 at.% Al. This range shifts to lower Re at lower temperatures. Partial isothermal sections at 1100, 1000, 790 and 700 °C are presented.
