Abstract

Quaternary alloy Al₈Cu₃FePr was melted in the nonconsumable arc-furnace under an argon atmosphere. The microstructure of the alloy was observed and analyzed by scanning electron microscope after high temperature annealing. It indicates that the alloy is a single-phase alloy with uniform chemical composition. Then, the crystal structure of Al₈Cu₃FePr alloy was determined by powder x-ray diffraction technology. The results show that Al₈Cu₃FePr is isostructural with Al₈Cu₄Pr crystallizes in the Mn₁₂Th-type structure, lattice parameters a = 8.8299(1) Å, c = 5.1582(1) Å, unit-cell volume V = 402.18 Å³ , formula units per unit cell z = 2, calculated density ρ_x = 4.981 g/cm³ , F₃₀ = 122.6(0.006, 46), the space group I4/mmm(No.139), and the reference intensity ratio value obtained experimentally is 1.20.
