Several deformed samples of a quasicrystalline phase T2 of an Al-Li-Cu alloy were studied by transmission electron microscopy. A quasicrystalline state, a modulated structure as well as a crystalline phase were observed by means of high-resolution techniques in the same region of a thin foil. As there is no evidence of boundaries to separate them, this implies that a continuous transformation from the quasicrystalline to crystalline states can occur in this alloy through structural modulation.
