説明:

The effects of different crystallographic orientations of the grains on damping capacity (tanδ) were investigated
using nano-dynamic mechanical analysis in pure magnesium, hexagonal close packed structure (HCP) Mg–20Sc (at.%), and body centred cubic structure (BCC) Mg–20Sc (at.%) alloy. In comparison to HCP Mg–Sc, the grain orientation has a significant impact on the tanδ of pure Mg and BCC Mg–Sc. Furthermore, the tanδ value of pure Mg at any given frequency were higher than those of HCP and BCC Mg–Sc samples due to the absence of the solute atom Sc.
