Effect of Microalloying on Damping Capacity of Magnesium Alloy

Magnesium alloys were prepared with the composite addition of V and Sc, moreover, the microstructure, phase composition and damping capacity of the alloy were tested. The results show that compared with the magnesium alloy without alloying elements of V and Sc, the composite additive alloying elements of V and Sc can markedly improve the damping capacity of the alloy, and make damping capacity increase by 149.52% at 20℃ when the frequency is the same at 0.6 Hz, and when the temperature is the same at 20 ℃, it could make damping capacity increase by 66.27% and 673.53% at the frequency of 0.2Hz and 1Hz, respectively.
