| Abstract: | Through determining the percent and appearance time of the carbide that exists in Fe-8%Cr and Fe-6%Cr steels during carburizing with different temperature and carbon potential,the curves of carbide extreme value (CEV) and carbon potential threshold (CPT) can be drawn. The effect of carbon potential temperature and Cr content on CPT and CEV are studied. |

| Keywords: | supersaturated carburizing CEV CPT |
