Decagonal phase in rapidly solidified Al6Co alloy

Abstract

Dunlap and Dini (1986) have found a decagonal phase instead of the icosahedral quasicrystal in a rapidly solidified Al₆Co alloy. The decagonal phase is similar but not identical to those found in Al₆Mn and Al₆Fe alloys. The crystalline phase coexisting with this decagonal phase is Al₉Co₂. The authors carry out a transmission electron microscopy study of the quasicrystal structure of the alloy.
