摘要：

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 xi-structure, which has a complementary counterpart hosted ill all F-type phases possessing phason lines as structural elements.
