Microstructural Characterization of Al-Cu-Fe Alloys in the Quasicrystalline Composition Range

Abstract:

The microstructural changes of six Al-Cu-Fe alloys; A)Al₆₂Cu_25.5Fe_12.5, B) Al₆₅Cu₂₀Fe₁₅, C)Al₆₈Cu₂₀Fe₁₂, D)Al₆₁Cu₂₆Fe₁₃, E) Al₆₅Cu_22.5Fe_12.5, F)Al₆₄Cu_25.5Fe_13.5, where the icosahedral phase is present, have been experimentally studied in both as-cast and annealed conditions by X-ray diffractometry, optical metallography, scanning electron microscopy and hardness tests. The resulting microstructures were characterized to investigate the effect of chemical composition on percentage of icosahedral phase and the changes in hardness obtained in this composition range. It was found that the B) Al₆₅Cu₂₀Fe₁₅ alloy showed the microstructure with major amount of icosahedral phase in as-cast condition with a value of 50 area%, while the A) alloy showed the highest amount of icosahedral phase. The hardness of phases after heat treatment increased with respect to alloys in as-cast condition, the hardness of y-Al₆₅Cu₂₀Fe₁₅ phase increased between 20-25%, while the l-Al₁₃Fe4 phase increased 9%.
