In a dislocation dynamics study of a single crystal under a loading–unloading sequence, the role of dislocation reaction was presented. The formation of prismatic dislocation loops was observed during the loading–unloading sequence, when allowing for cross-slip. The cross-slip probability strongly affected the microstructure rearrangement.
