Novel metadislocation variants in orthorhombic Al–Pd–Fe Original Research Article

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.
