Effect of Ce on the High Temperature Mechanical Properties of Martensitic Stainless Steel

Article Preview

Abstract:

The effects of Ce on the inclusions and the high temperature mechanical properties of 2Cr13 stainless steel were studied. The results show that the morphologies and sizes of inclusions in 2Cr13 stainless steel are changed, and Ce played a very good role of modifying inclusions. The high temperature strength of 2Cr13 stainless steel is improved obviously by Ce. In comparison with 2Cr13 stainless steel without Ce, the high temperature strength of 2Cr13 stainless steel with Ce is increased 18.18% at 1273K, respectively.
