Identification of a new hexagonal phase in the Al-Cu-Re system Academic Article uri icon


  • Particles of an unknown intermetallic phase with the approximate composition Al 65 Cu 25 Re 10 were observed in a ternary Al–Cu–Re alloy. The structure of this phase was investigated in a transmission electron microscope using the precession electron diffraction (PED) technique. This phase has a hexagonal unit cell with lattice parameters a= 11.029 (6) and c= 12.746 (1) Å; its crystal symmetry can be described by the P6 3 (173) space group.
