The internal friction of Mg was studied at 4 kc/s and 40 kc/s as a function of temperature (4.2-3OO"K), plastic deformation, crystalline orientation, heat treatment and impurity content. In pre-strained polycrystalline samples a peak was observed at 20Β°K which annealed out readily at 300"K, and a v
## Granato and Lticke is modified for metals with high stacking fault energy. It is assumed that the most abundant impurity atom species interacts only with the edge component of each dislocation. For this model the hysteretic, or frequency independent, damping initially increases linearly with st
