Summary

This study examined how cyclic loading affects internal friction in magnesium alloys AZ31, AZ61, and AZ91 after homogenization annealing. Researchers found that microplastic deformation processes and energy dissipation varied among the alloy compositions.

The article is aimed on the analysis of the influence of cyclic loading on the internal friction measured on magnesium alloys, especially AZ31, AZ61 and AZ91, after homogenization annealing. Microplastic processe and dissipation of energy within the alloys are evaluated and investigated by internal friction measurements. In experimental measurements resonance method was used, which is based on continuous excitation of oscillations of specimens. Measurements were performed at final excitation voltages of 5 V, 6 V and 7 V.
