DETECTION AND IDENTIFICATION OF ULTRAFINE NONMETALLIC INCLUSIONS IN STEEL

摘要

The detection and identification of finely disperse (micronic and submicronic) oxides in steel using scanning and emission electron microscopes is considered. The observations are made at high temperatures, up to the melting point of the sample. Finely disperse oxides are detected thanks to the amplification of secondary electron emission under the action of the electronic field.
