Abstract

From the behavior of the critical stress of amplitude-dependent internal friction as a function of concentration and temperature, it is concluded that the level of the first critical stress is governed by resistance to the translation of dislocations offered by impurity atoms in the neighborhood. The interaction between moving and forest dislocations makes a large contribution to the dissipation of vibration energy at high amplitudes of deformation.
