Research Abstract

The distribution of stress/strain in <111> aluminum single crystals was measured at as-grown, 8% tensile deformation, and post-deformation annealing stages, by using synchrotron radiation. A typical as-grown single crystal was composed of three sub-grains bounded by sub-boundaries. After 8% tensile deformation, the sub-grained structure remained. The residual stress approximately of 5MPa was randomly distributed in each sub-grain. The crystal quality of recrystallized grains formed after 753K annealing was better by far than that of the as-grown crystal. By using the synchrotron radiation, it was possible to measure the stress/strain with very high resolution and accuracy.
