The atomic structure of the icosahedral phase is characterized both by long-range icosahedral orientational order and by a quasiperiodic translational one. Because the long-range orientational order generates anisotropy, it is natural that the icosahedral phase forms a crystallographic texture during solidification through preferred growth and/or nucleation. No texture was, however, observed in melt-spun quasicrystalline Al{sub 74}Si{sub 6}Mn{sub 20} by x-ray photography and diffractometry. The present work reports the observation of textures by pole figure measurements for Al-Mn based and Al-Li-Cu quasicrystals produced by melt-spinning.
