Abstract

The inter-metallic phase with composition Al_0.88Cu_0.94Fe_0.18 was synthesized by high-temperature sinter-ing of a mixture with initial chemical composition Al₇₈Cu₄₈Fe₁₃. Al_0.88Cu_0.94Fe_0.18 adopts the CsCl structure type in space-group Pm m. The structure analysis revealed that one site is co-occupied by Al and Cu with a ratio of 0.88 (5):0.12 (5) and the other is co-occupied by Fe and Cu with a ratio of 0.2 (4):0.8 (4). The Al/Cu⋯Fe/Cu separation is 2.5465 (13) Å.

Keywords: Al–Cu–Fe system; crystal structure; high-temperature sintering; β phase.
