  A study of the Al-rich part of the Al–Re alloy system

  摘要：

  The Al-rich part of the Al-Re phase diagram was reinvestigated by scanning and transmission electron microscopy, powder X-ray diffraction and differential thermal analysis. The earlier reported Al12Re, Al6Re, and Al11Re4 phases were confirmed. Close to the Al4Re composition a high-temperature h-Al4Re and a low-temperature 1-Al4Re phase were found to be formed at slightly different compositions. Both exhibited compositional ranges. A new phase was revealed close to the Al3Re composition. The Al11Re4 phase is formed congruently at 1650 degrees C, Al3Re peritectically at 1610 degrees C, h-Al4Re peritectically at 1410 degrees C, 1-Al4Re peritectically at similar to 1000 degrees C, Al6Re peritectically at 813 degrees C and Al12Re peritectically at 746 degrees C. Finally, the Al12Re-(Al) eutectic is formed at 658 degrees C. The Al3Re and h-Al4Re are decomposed by eutectoid reactions at similar to 946 and 833 degrees C, respectively. The structure of the h-Al4Re phase has not yet been clarified, but it is distinctly different from the Al4W phase suggested earlier. The structure of 1-Al4Re was confirmed. The Al3Re phase was found to have a monoclinic structure with a = 0.5180(4) rim, b = 3.97641(9) nm, c = 0.4955(3) nm and beta = 99.55(7)degrees. (c) 2007 Elsevier B.V. All rights reserved.

  The binary system rhenium-aluminium is characterized by the occurrence of seven intermediate phases and two eutectics. The intermediate phases are: Re2Al, ReAl, Re4Al11, ReAl4(h), Re8Al33-x, ReAl6, and ReAl12. They form at 1494 +/-4 degreesC (peritectoid), 1060 +/- 10 degreesC (peritectoid), 1665 degreesC (congruent melting), 1404 +/-4 degreesC (incongruent melting), 1008 +/-4 degreesC (polymorphic transformation), 803 +/-4 degreesC (incongruent melting), and 750 +/-4 degreesC (incongruent melting), respectively. Crystal structure data and lattice parameters for all these phases are given. The two eutectics occur (1) at 1655 +/-3 degreesC and similar to 74 at%Al, and (2) at 658 degreesC and > 99 at%Al.
