抄録

The purpose of this paper is to understand controlling factors of separations parallel to the rolling plane developed in charpy specimens when rolling is extended in α+γ two phase regions.<BR>Main results are as follows:<BR>1) Separation were found to be enhanced by the development of {100} and {111} textures, the formation of large texture bandings consisted of a group of ferrite grains having a common crystallographic orientation, and the presence of the local plastic flow at the notch root preceding complete fracture.<BR>2) Separations were found to increase the area of intergranullar fracture as the texture developes.<BR>On the basis of these results it is suggested that separations may be formed by the initiation of the crack along the interface between {100} bandings and {111} bandings resulting from the anisotropic plastic flow of these bandings.
