The crystallite orientation distribution analysis was applied to the study of the development of the rolling textures in low-carbon steels. It was found that the constraining effect of the grain boundary remarkably influences the rolling textures of polycrystalline iron. This enhances the crystal rotations, which would not be expected to occur in single crystals; and grains having the {111 }(112) orientations are forced to rotate about the (111) axes lying in the sheet normal direction toward the {111} (110) orientations. This is the origin of the (111) fiber texture normally found in the rolling textures of low-carbon steels. The presence of the partial fiber texture having the (110) axes inclined 30 deg from the sheet normal toward the rolling direction could not be confirmed.
SynopsisThe effect of crystallographic texture on the anisotropies of strength and toughness of the control-rolled high tensile steels was quantitatively investigated . The effect of the textures on the anisotro.bies of yield and tensile strees could be accurately evaluated with H osford and B ackofen's method, if fine de tails of textures were properly taken in to account. The anisotropies of toughness were found to be qualitatively related with the dis tribution of { 100} cleavage plane. 1 t was f urther fo und that among the main components of the textures of tlzese steels, {3 1J }<01J > orientations not only enhanced the difference in stmlgth between L (OO) and C(900) directions, bu t also reduced the toughness at 45° direction, whereas {332}< 113 > orientations gave rise to a weak anisotropy and better average strength and toughness . T hus, f urther im/Jrovemen t in strength and toughness might be eX/Jected,ij /Jreferential development of {332}< 113 > orientations was to be achieved .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
