Observation of stacking faults in a scanning electron microscope by electron channelling contrast imaging

Abstract

Abstract The electron channelling contrast imaging technique was applied in a scanning electron microscope equipped with a field emission gun and high beam current mode for imaging stacking faults, in particular in two different variants of cast TRIP steel after tensile and cyclic deformation. Besides well developed deformation bands, individual stacking faults with low dissipation width were observed in the metastable austenitic matrix.
