Summary
Upon annealing, the small angle X-ray scattering in deformed copper first increases and then decreases in the angle range between 10 and 30 minutes of arc. This result combined with Blin and Guinier's observation that under similar conditions the scattering decreases in the range of 1 1/2 to 7 degrees may be interpreted as an indication of clustering of defects prior to their disappearance.
