Abstract

Significant neutron peak broadening was observed in situ underneath the tool of friction stir processing (FSP) in 6061-T6 aluminum alloy. Such broadening was correlated to the dislocation density and subgrain size by using peak profile analysis methods. The high dislocation density of about 1.3×10 15 m -2 underneath the FSP tool sharply decreases to 1.0×10 14 m -2 outside the tool. The quantitative determination is consistent with the high-resolution x-ray and TEM results. © 2012 Elsevier B.V. All rights reserved.
