Abstract

Toward establishing in-situ electron channeling contrast imaging (ECCI), we present three insights in ECC images, which are related to {111} surface traces in face-centered cubic alloys. For this purpose, ECCI was carried out under tensile loading in an austenitic steel. First, dislocation slip and stacking fault formation during deformation can be distinguished in ECCIs. Second, crystallographic orientation can be determined by three {111} traces in ECCIs. Third, shrinkage of stacking faults on {111} planes under unloading was observed by in-situ ECCI even in a smooth specimen, which implies a significant difference between in-situ and ex-situ observations.
