Abstract

The changes in the microstructures associated with plastic deformation and strain/stress were measured using the strain scanning method with hard synchrotron radiation. Aluminum single crystals tensile-deformed along the <111> direction exhibit a macroscopically uniform multiple-slip without deformation bands. Plastic deformation has an insignificant effect on lattice spacing, and is likely responsible for the relatively uniform distribution of internal stress with a small absolute value. With regard to the crystallographic orientation, the rocking curves in the as-annealed sample differed with position, strongly suggesting that mosaic structures exist in a single crystal. In the 8% tensile-deformed sample, mosaic blocks are divided into smaller size. The increase in the number of mosaic blocks with deformation causes broadening the rocking curve and FWHM of the profile.
