Abstract

Polycrystalline quasi-crystals of icosahedral Al70Cu20Fe10(i-Al70Cu20Fe10) were prepared by thermal explosion (TE) of mechanically activated mixture of Al, Cu, Fe powders doped with AlCu. The effect of AlCu dopant was studied by XRD, field emission scanning electron (FESEM), optical microscopy (OM), atomic emission spectroscopy (AES), and energy-dispersive X-ray microanalysis (EDX). The synthesized i-Al70Cu20Fe10 and intermetallics (Al3Fe, Al2Cu) show soft ferromagnetic and paramagnetic properties, respectively.
