摘要：
In this dislocation dynamics study of a single crystal under a loading-unloading sequence, the role of dislocation reaction is presented. The formation of prismatic dislocation loops is observed during the loading-unloading sequence, when allowing for cross-slip. The cross-slip probability strongly affects the microstructure rearrangement. (c) 2005 Elsevier B.V. All rights reserved.
