摘要：
The effect of Ce on modifying inclusions of 253MA heat resistance stainless steel was studied by metallographic examination, SEM and electron spectroscopy. Thermodynamic calculation was used to analyze the formation and transformation of RE inclusions in 253MA heat resistance stainless steel. The result shows that Al2O3 and MnS can be entirely replaced by Ce2O2S and CeS that are spherical.
