Abstract

The dislocation multiplication behavior of AZ61 magnesium alloy during cyclic bending vibration was investigated. The results show that with the increase of stain amplitude and shear stress, the process of dislocation multiplication behavior contains dislocation slipping, dislocation multiplication and dislocation extension, and dislocation multiplication phenomenon accords with Frank–Read source mechanism. At last, the mobility dislocation number and the dislocation density in AZ61 magnesium alloy increase significantly with the increase of stain amplitude.
