摘要
本文利用透射电子显微镜对５５ＳｉＭｎ２Ｍｏ钢正火后的显微组织进行观察发现：该钢正火后得到Ｂ／Ｍ复相组织，其中马氏体包括板条马氏体和孪晶马氏体；而贝氏体为非典型的变态下贝氏体组织。
A study of microstructure of 55SiMn2Mo steel after normalizing by TEM.The results shows that the bainite and martensite duplex structure were obtained,the martensite includes Lath martensite.and twin martensite,but the bainite is abnormal bainite.
