ELECTRON MICROSCOPY OBSERVATIONS OF THE DISLOCATION STRUCTURE IN LITHIUM CRYSTALS

Abstract

Li thin foils of 1‐μ thickness or more were observed by conventional electron microscopy with 100‐keV electrons. The dislocation structure has been analyzed at 300°K and around 100°K in the bcc phase of Li. Dislocation slip planes are of the {112} types and most dislocations are parallel to 〈110〉 directions.
