► Point defects induced during milling leading to an order–disorder quasicrystal transition. ► Nanoquasicrystalline regions of 12 nm are obtained. ► Highly ordered i-phase with high symmetry transforms to a crystalline phase of intermetallic character and lower symmetry. In this investigation the Al...
