摘要: 用扫描电镜、透射电镜和电子探针研究Mg-Al复合变质奥─贝钢中共晶体的团球化结果表明,团球状共晶体是由于C、Mn、Si偏析,于凝固后期在奥氏体校晶间形成的渗碳体和奥氏体伪共晶组织,共晶体结晶时的异质核心是MgS.团球化是异质核心和变质元素影响共晶体的结晶方式
关键词 Mg—Al奥氏体─贝氏体共晶体团球化    
Abstract:Nodularization of eutectic in austenite-bainite steel modified by Mg and Al have been investigated by means of TEM,SEM and EPMA.Results show that the nodular eutectic is pseudo-eutectic of austenite and Fe3C, which is formed between austenite dendrites at
Key wordsMg-Al    Austenite-bainite    nodilizing of eutectic
