Long-period one-dimensional antiphase structures with average domain sizes of non-integral multiples (M=1.33 and M=1.50−1.91) of the basic L12 cell, existing in the Al3−xTi1+x(0<x>0.33) alloys, were studied by electron diffraction, high-resolution electron microscopy and X-ray diffraction. The mode of mixing of M=1 and M=2 domains was revealed and the nature of lattice modulation associated with the antiphase structure was clarified. A new type of superstructure Al5Ti3 was also studied by high-resolution electron microscopy and the structure model proposed previously was verified.
