Crystal structure, disorder and composition of the 2/1 approximant in the Al–Mg–Zn system revisited

The τ1 and τ2 phases in the Al–Mg–Zn system are famous examples for complex intermetallic alloy phases. They are 1/1 and 2/1 approximants of a quasicrystalline phase. The crystal structure of the τ2 phase has been studied several times but the reported results are inconsistent. In this work, the τ2...
