Analyse radiocristallographique de la repartition de textures en fonction de I'epaisseur de la tole dans du fer armco lamine a froid

摘要

The depth distribution of the crystallographic texture of a cold rolled low carbon steel was investigated using X-ray diffraction. In contrary to literature, the material under investigation showed a complex distribution of the texture with depth. At and near the surface a typical rolling texture {001}<110> with a spread of about ±60° around the <001> axis was found. In deeper regions, the rolling texture was followed by a Goss texture {110}<001> with a maximum at 25% of the thickness below the surface. In the sample centre, however, a <111> fibre texture with the fibre axis in normal direction ad a small amount of {001}<110> rolling texture were observed. Between these texture components smooth transitions occur.
