We have investigated the effect of superplastic carburizing on the texture of duplex stainless (DS) alloy. The diffusion velocity of carbon in the superplastic DS alloy is much higher than that in non-superplastic DS alloy that has the same chemical composition. In carburized layer, the segregation of Cr can be observed and Cr-carbides precipitate at the grain boundary, in particularly, the triple-point intersection of grain boundaries. The precipitation of Cr-carbides in stainless alloys is disadvantageous because it causes a decrease in its corrosion resistance.
