OBSERVATION ON INTERFACIAL MISFITTING DISLOCATION IN META-BAINITE
准贝氏体界面错配位错的TEM观察

The misfitting dislocations at the interface between bainite ferrite and retained austenite in upper meta-bainite and lower meta-bainite, which formed in Si-containing steel, were studied by using transmission electron microscopy. It was found that they were mixed dislocations. Therefore, the interface can slip conservatively in the normal direction of its plane. The bainite may be formed by martensitical shear mechanism.
