Study of phase equilibria in the Al-Pd-Re system

Scanning and transmission electron microscopy have been combined with x-ray diffraction to examine the phase equilibria in the Al-Pd-Re system at 1000 degrees C for compositions front 50 to 100 at. % Al, and the corresponding isothermal section has been constructed. The binary monoclinic Al3Re phase has been observed for the first time. It is confirmed that there is a stable icosahedral phase in this system. The boundaries to its homogeneity region have been determined and the phase equilibria in which it participates
