The carbide precipitation and chromium distribution in low-energy coincidence site lattice (CSL) segment induced by twinning at random boundary were investigated. Thermomechanical treatment increased the corrosion resistance by increasing the frequency of special grain boundaries. Analysis showed that there existed only smaller chromium depletion in the low-energy CSL segment than that at random boundary for no carbide precipitation.
