Abstract
In addition to the dislocation-relaxation mechanisms discussed in the previous section, there are other ways in which dislocations may contribute to the overall damping. It has been known for some considerable time that the ‘background’ damping observed at all temperatures could be attributed to dislocation motion, and it is possible to explain, at least in a qualitative manner, the way in which this damping is affected by a great many variables such as frequency, temperature, impurity and defect concentration, by considering it as being due to dislocations.
