A large number of twins was found in bainitic midribs for first time. Twins in midribs (M-M) as well as retained austenite (Ar) are deformation twins formed by coordinating uniform shear deformation as bainitic ferrite lath grows, twins in bainitic ferrite (BF)mainly are those inherited in retained austenite as BF thickens by shear mechanism in broad face. and twin planes correspond to the interface ledges, which shows ledges can not migrate along side direction of broad face. Based on the results, a model of twin formation in lower meta-bainite was suggested.
