| Outline of Final Research Achievements |
5083 aluminum alloy was cold-rolled at a reduction rate of 85 % by a dull roll and then annealed for a short time. As the result, the grains with <111>//ND were easily formed. Mulch passes cold-rolling was carried out with raising reduction rate for one pass so that the grains with <111>//ND were increased. However, they existed only on the surface of the specimen. Moreover, they were invaded by recrystallized grains growing from the inside of the specimen and the cold-rolling texture was constructed. Deformation microstructure under the surface of the specimen was similar to the cold-rolling texture. The recrystallized grains having the orientations of the texture were preferentially grown. It was concluded that these prevented the forming the <111>//ND texture.
