From Quasicrystals to Crystals with Interpenetrating Icosahedra in Ca-Au-Al: In Situ Variable-Temperature Transformation.

The irreversible transformation from an icosahe-dral quasicrystal (i-QC) CaAu[sub 439]Al[sub 161] to its cubic 2/1 crystalline approximant (CA) Ca[sub 13]Au[sub 56 31]([sub 3])Al[sub 2169] (CaAu[sub 433]([sub 1])Al[sub 167], Pa3 (No. 205); Pearson symbol: cP728; a = 23.8934(4)), starting at ~570 °C...
