The microstructure of a 26.6% chromium white iron had been characterized in a previous study. An observation within this study confirmed the literature view that the eutectic (Fe,Cr)7C3 carbide phase within high chromium content ferrous alloys always contained crystalline faults, regardless of the heat treatment. A kinematic model was advanced to explain how mechanical stacking faults occurred within (Fe,Cr)7C3 carbide. The kinematical model was compared to the findings obtained from a high resolution transmission electron microscope.
