Networks of the {110} shear plane family in the Al5CuLi3 crystal structure have been observed during the phase transformation from AlCuLi icosahedral phase to the crystalline phase, i.e. Al5CuLi3 crystal. HREM images of the shear planes are reported along both [111] and [001] directions which establish the shear vectors uniquely. Structural models for the shear planes, intersection areas and translation domains have been symmetrically proposed and are in good agreement with experiments.
