Abstract
Serrated flow was investigated in binary Al-Li single crystals treated from naturally aged to overaged conditions. Serrations were observed during the deformation of crystals in artificially aged conditions, bu t not in naturally aged condition. The number of serrations with small stress drops as well as short elapsed time increases in peak-aged con dition as compared to underaged or overaged conditions. It is indicate d that shearing of delta' particles plays a key role in the discontinu ous deformation of AI-Li single crystals. (C) 1998 Published by Elsevi er Science S.A. All rights reserved.
