The alloy is found to contain mainly Al_3Zr superlattice phase, η′precipitate phase ard Al_?-Cu_? Fe constituent phase. The η′phase has a C-face centered orthorhombic crystal structure with a=0.492 nm, b=0.852 nm and c=0.701 nm. The orientation relation- ship between η′phase and matrix is determined as (101)_m//(010)_(η′), [111]_m//[001]_(η′).
