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.

Recent progress in the material sciences has led to an increasing amount of interest in the role of textures for the behaviour of materials and in the mechanisms controlling the texture formation. This development was supported by a rather powerfull development taking place in the area of texture studies itself: Besides the usual, more qualitative, characterization of a texture by pole figures a fully quantitative description by a three-dimensional orientation distribution function (ODF) has been increasingly applied. There are two sides to the problem of quantitative representation of textures. One involves the mathematical technique associated with the acquisition of an ODF, and its transforms, from the experimental data, whereas the other concerns the methods of a rational description and interpretation of an ODF. The fust side can be considered from the practicaf point of view as experimental-data processing which is accomplished by a computer and is sort of a continuation of the measurement itself. Much attention has been paid to this problem, particulary by Bunge, who has written up achievements in this field in this extensive monograph /1/ and in conference proceedings /2/. There is also avaiable a rather detailed presen· tation of a system of subroutines written in Fortran /3/ which allows standard computations to be made without having to go into the mathematical details of the method.

Many important properties of a polycrystalline material are known to depend on the orientation of the crystallites. The distribution of these orientations is referred to as its texture. During the past decade a remarkable sophistication of experimental methods, of texture determination and texture representation has been achieved, and, at the same time, a fast development of texture applications, for the improvement of materials propert- ies and for investigating the processes underlying the texture formation has taken place. As a consequence of this increasing interest in texture analysis and control in research and practice, world wide conferences on textures of materials were established in order to master the increasing flood of ideas and results. Until now five of such meetings were held, namely in Clausthal (1969), Cracow (1971), Pont-a-Mousson (1973), Cambridge (1975), and in Aachen (1978). The sixth conference of this series will be held in Tokyo. The present two volumes contain the refereed proceedings of the 5th International Con- ference on Textures of Materials (ICOTOM 5).It was held from March 28-31, 1978 at the Institut fUr Allgemeine Metallkunde und Metallphysik of the Rheinisch-Westfiilische Technische Hochschule Aachen. The 150 participating scientists (47 from Germany, 103 from 19 other countries) heard 16 invited and 86 contributed papers. Topics of the conference were all important areas of current research and application: texture analysis, experimental methods, deformation textures, recrystallization textures, transformation tex- tures, textures of minerals, textures in steels, textures in special applications, influence of the texture on physical and mechanical properties.
