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
