（１２３）［６￣３￣４］方位のアルミニウム単結晶の再結晶集合組織

Abstract

The rolling and recrystallization textures of the aluminum single crystals with the (123) [634] orientation were examined by the ordinary X-ray pole figure technique. The initial orientation was sharply maintained as the main component of the rolling texture up to the highest 99% reduction. The orientation spread shown by the iso-intensity lines below level 1 increased with an increase in the rolling reduction. The formation of the deformation structure of a rotated cube orientation and the symmetrical component of the initial orientation with respect to the transverse direction were detected in the specimen of the highest reduction. The recrystallization textures were mainly composed of the rotated cube orientation after cold-rolling more than 95%. None of the other seven variants were observed. Thus, the rotated cube texture in aluminum single crystals with the stable orientation was concluded to be formed by the preferential nuclsation from the deformation structure near (001) [100] orientation.
