N2 - We report experimental evidence on redistributions of alloying elements in a partially quasicrystallized Zr 65Al 7.5Ni 10Cu 7.5Ag 10 bulk metallic glass. Energy-filtered elemental maps show that the partitioning of silver, zirconium, and aluminum occurs in the quasicrystallized glass. Silver is found to enrich into quasicrystals, but zirconium and aluminum are slightly depleted from the quasicrystals. These observations suggest that the amorphous-to-quasicrystal transformation in this alloy is not a simple polymorphous reaction and a long-range diffusion is involved in the devitrification, probably prior to the quasicrystallization.
