Novel metadislocation variants in orthorhombic Al–Pd–Fe

We report on the observation of new variants of metadislocations in the orthorhombic complex metallic alloy phase Al–Pd–Fe. At Fe contents above about 3 at.% we find a novel type of metadislocation in the ξ-structure, which has a complementary counterpart hosted in all ε-type phases possessing phason lines as structural elements.
