Large AlCuLi single quasicrystals with triacontahedral solidification morphology

Abstract

The discovery of icosahedral symmetry in rapidly solidified Al-Mn alloys1 has stimulated considerable research activity mainly because it appeared to violate the classical rules of crystallography. Hence, it left the field open for numerous reports on rapidly-solidified phases with icosahedral symmetry in aluminium based alloys. However, a challenging goal for materials scientists has always been the fabrication of large quasicrystals that would allow further investigation of the crystallographic and physical properties of this new form of material. This paper reports the first evidence of triacontahedral solidification morphology of large quasicrystalline dendrites within an as-cast Al-Cu-Li alloy with composition close to that of the Al6CuLi3 phase.
