Full text linkTHE ICOSAHEDRAL Al-Li-Cu PHASE
No full textThe common grain boundary precipitate in commercial Al-Li-Cu-(Mg) alloys which is responsible for detrimental precipitate-free zones is the icosahedral Al-Li-Cu phase designated T2. The present work discusses the growth of the T2 phase as large, faceted single quasicrystals and reviews results of morphological analyses and high resolution x-ray studies. These results confirm the icosahedral point symmetry of the phase and allow comment on the atomic structure and the disorder which appears to be inherent in the phase
