FIELD ION MICROSCOPY OF IRON WHISKERS

Abstract

The field ion microscope images of iron whiskers from various origins were observed and differentiations between iron whiskers and specimens made of pure iron wire were studied. Indications of crystal defects such as screw dislocations and axial disordered core structures were found. The influence of various gases on the iron surface under the extremely high electric field and the diffusion of potassium ions into the iron lattice was observed. The operation of the field ion microscope with neon gas gives certain advantages for the study of easily field evaporating metals such as iron.
