Effect of the Cyclic Tensile Component of Loading on the Dislocation Structure of AMg6 Alloy

We study the effect of the cyclic component under combined tension of specimens of AMg6 alloy on the evolution of the microstructure of the material along the neck of the specimen. We discovered that cyclic loading imposed on quasistatic loading results in a significant increase in dislocation density. The cyclic component of tension initiates the appearance of additional mobile dislocations, which leads to a greater strain under the same stresses.
