Abstract

The formation of the quasicrystalline phase Al_62.₅Cu₂₅FC₁_2.5, by twin rolls rapid solidification technique has been investigated. The obtained phases are cauterized by XRD, Differential Thermal Analysis and electrical resistivity measurements. The effect of milling on the sample produced by rapid solidification is also examined.
A quenched sample, a quasicrystalline (i-phase) is present in a relatively high volume fraction, in addition to two other phases that are most likely Al₂Cu to be phase and Al₇Cu₂Fe phase (𝟂-phase). The milled samples does not give a single quasicrystalline phase, but the milling tends to stabilize the pre- existed i-phase.
