USING ECCI AND EBSD TO STUDY THE MICROSTRUCTURE OF HARDMETALS

摘要

In this study, electron channelling contrast imaging (ECCI) and electron backscattered diffraction (EBSD) are used to understand the dislocation networks in polished tungsten carbide-cobalt (WC-Co) hardmetals. These scanning electron microscopy (SEM) techniques utilised in both an SEM and electron microprobe (EPMA) are applied as an alternative to transmission electron microscopy (TEM).
