Abstract
Electron channeling contrast (ECC) imaging in the scanning electron microscope (SEM) provides a useful method of characterizing the microstructural evolution of wrought ferritic stainless steel. The ability to examine bulk specimens in the SEM without involving the tedious etching procedures normally associated with light microscopy is demonstrated. Recovered and recrystallized domains are clearly distinguished by ECC, and the sensitive relationship between grain orientation and grey-level contrast gives rise to a clear delineation of the overall recrystallized grain structure. Artifacts sometimes introduced by the examination of etched microstructures are avoided, and the continuous assessment of the microstructure in the through-thickness direction is easily accomplished in a single sample.
