HRTEM observation of misfit dislocations at non-faceted Al-Pb interfaces

Al-Pb samples containing 1 at.% Pb were produced by high-energy ball milling and investigated by high-resolution transmission electron microscopy. The Pb inclusions embedded in an Al matrix exhibit a non-faceted, curved morphology. Dislocations have been found to accommodate the misfit of about 22%...

Description
Summary:Al-Pb samples containing 1 at.% Pb were produced by high-energy ball milling and investigated by high-resolution transmission electron microscopy. The Pb inclusions embedded in an Al matrix exhibit a non-faceted, curved morphology. Dislocations have been found to accommodate the misfit of about 22% at the Al-Pb interfaces. Burgers circuits, drawn around these misfit dislocations, exhibit closing failures of the type a 0 /4⟨211⟩.
