The application of electron channeling contrast imaging (ECCI) technique to the study of polycrystalline austenitic steel is presented.

Specifics of the ECCI technique for near surface defects observation are explained. Practical examples of the use of ECCI for study of dislocation structure of fatigue test samples are shown.

Usage of a 'rocking beam' technique for electron channeling pattern (ECP) and selected area channeling pattern (SACP) acquisition on polycrystalline material is described.
