Internal Friction and Ultrasonic Attenuation in Crystalline Solids: Proceedings of the Fifth International Conference on Internal Friction and Ultrasonic Attenuation in Crystalline Solids August 27-30, 1973, Aachen, Germany

The methods of internal friction allow the study of numerous structural features and processes in solids. In many cases these methods are superior to other means of investigation or even the only ones able to provide the desired information. For these reasons, and especially since the appearance of Clarence Zener’s Elasticity and Anelasticity of Metals in 1948, the interest in the field of internal friction has been increasinq strongly. Both the depth of understanding of known phe nomena and the area of application of internal friction to the investi gation of new effects qrew quickly. As a consequence, wor~wide international conferences on internal friction were established. Until now five meetings took place, namely at Brown University, Providence R.I. (1956 and 1969), at Cornell University, Ithaca N.Y. (1961), at the University of Manchester (1965) and at the Technische Hochschule of Aachen (1973). The sixth will be held in Tokyo.
