Damping and dynamic recovery in magnesium alloys containing strontium

This article reports evidences related to the effect of strontium on damping and dynamic recovery of novel extruded magnesium alloys. Dynamical mechanical analyses demonstrate a significant plateau region on storage/loss moduli, as well as damping values. Post-mortem electron back scatter diffraction and kernel average misorientation analysis showed that these experimental results are related to both changes in texture and crystallographic recovery due to twinning and pronounced slip activity at higher temperatures.
