摘要

Ternary Al-Cu-Ir phases, isostructural to the Al-Cu-Rh w and C_2 phases, were found to be around the Al_70Cu_20Ir_10 and Al_60Cu_15Ir_25 compositions, respectively. Using powder X-ray diffraction, the former was found to have a tetragonal structure (space group PAImnc) with a = 6.4142(9) A and c= 14.842(4) A, and the latter has a cubic structure (space group Fm3) with a= 15.3928(6) A.
