主　　题：steel metallurgy inclusions ferrite austenite grain size 

摘      要：The change of inclusions and microstructure of 16Mn steel treated by Ce were observed,and the effect of austenitizing temperature on the microstructure was also *** results show that the inclusions are transformed from Si-Mn-Al composite oxide and MnS into AlCeO3,Ce2O2S,and MnS composite inclusions after being treated by *** of intragranular ferrites are formed in 16Mn steel containing～0.017wt% Ce.A large amount of intragranular acicular ferrites are formed after being austenitized for 20min at 1473 *** prior austenite grain size fit for the formation of intragranular acicular ferrites is about 120μm.
