      abstract     = {We investigate dislocations in the complex metallic alloys
                      T-Al-Mn-Pd and T-Al-Mn-Fe using high-resolution
                      aberration-corrected scanning transmission electron
                      microscopy. The dislocations consist of a large core and
                      separated escort defects [1]. Upon movement, dislocations
                      and escort defects locally transform the material and
                      introduce stacks of planar faults which represent a slab of
                      a different but related structure. Deformation modes
                      involving glide and climb are observed. We find different
                      types of dislocations with Burgers vectors (b) over bar =
                      -(-tau)(-n)(0 0 1), with n = 2, 3, 4. They are associated to
                      two, four and six planar faults, respectively, and are
                      identified as metadislocations. The structural connection
                      between metadislocations in the present phase and those in
                      R-, epsilon(6)-, and xi-phases is discussed. (C) 2011 Acta
