结果讲明,该钢板的析出物要紧是钛化物,析出顺序为:TiN,TiS,Ti4C2S2,AlN,并存在 Cu 元素晶界偏聚现象
关键词 透射电镜;耐大气腐蚀钢;析出物 Study on the Precipitations Characterization of 09CuPTiRE Steel XIA Dianxiu1,GUAN Xiaojun1,SUN Hao2,ZHOU Lanju2,Li Xingfang1(1 Shandong University's material science and project institute, Jinan 250061 ,China2 Technology center of Jinan Iron & Steel Group, Jinan 250101, China)Abstract The precipitations of the 09CuPTiRE steel is studied by TEM and SEM
The result shows that: the major precipitations are compounds containing Ti,the sequence of the precipitation is basically: TiN,TiS,Ti4C2S2,AlN,and Cu tends to segregate in the grain boundary
