Title: Bulk amorphous (Mg{sub 0.98}Al{sub 0.02}){sub 60}Cu{sub 30}Y{sub 10} alloy

Abstract

Recently, Inoue and Masumoto have found that Mg-Cu-Y alloys show high glass-forming ability (GFA), hence making it possible to produce bulk amorphous samples of such alloys. The aim of the present work was to characterize in some detail one of these new bulk amorphous alloys, (Mg{sub 0.98}Al{sub 0.02}){sub 60}Cu{sub 30}Y{sub 10}. Its stability and crystallization process was examined by using x-ray diffraction (XRD), differential scanning calorimetry (DSC) and small-angle neutron scattering (SANS). One finding was the formation of nanocrystalline particles on annealing. It was also found that the addition of Al increases the hardness.
