Abstract:
A review is given of the type of information concerning mechanical properties of crystals obtainable from internal friction measurements. The methods of measurement, together with their advantages, disadvantages and limitations are outlined. Results are described within a framework in which defect interactions are considered from the •particle• point of view. A selection of results found by internal friction techniques which are often difficult to obtain by other methods is described. These include recent measurements which have contributed to the understanding of dislocation interactions with point defects and phonons, as well as dislocation distributions in deformed materials.
