摘　　要：开展相变研究具有理论意义和工程应用价值。采用SEM、TEM、STM、XRD、LSCM等设备研究观察了钢铁材料中的固态相变,发现许多新的试验现象,如珠光体表面浮凸、钢中马氏体层错亚结构、低碳马氏体中的孪晶、位向关系偏差、新观察到的形核地点等。It has theoretical significance and engineering application value to carry out the research on phase transformation.Solid-state phase transformation in iron and steel was investigated by means of SEM,TEM,STM, XRD and laser scanning confocal microscopy （LSCM）.A lot of experimental phenomena,such as surface relief of pearlite,fault substructure of martensite in steel,twin crystal in low-carbon martensite,deviation of orientation relationship,newly observed nucleation site and so on,were found.
