International Conference on Vacancies and Interstitials in Metals 2

The International Conference on Vacancies and Interstitials in Metals,Jülich 1968, has been organized with the intent to give a generalsurvey of our present knowledge on point defect phenomena in metals.Although the rapid development of this field in the early sixtiesseems to have slowed down, at present many of the fundamental problemsare still unresolved. This holds especially for the problem of defectidentification and the interpretation of annealing stages. Furtherprogress is to be expected mainly from the application of experimentaltools which give more detailed information about the structure of thesingle defect and from a better correlation of experiments in whichthe defects have been generated by different techniques e.g. quenching,particle irradiation, plastic deformation.For this reason, particular attention is focused on reviewing theinformation accumulated from equilibrium, quenching, irradiation andplastic deformation experiments employing the more common techniques,as well as to the search for new, more powerful tools for the studyof interstitials and vacancies.The scientific program of the conference is based on about 25 invitedlectures (with ample discussion time) which are thought to cover theessential topics of the field. Abstracts of these lectures, in so faras they have been received, are included in the present report. Thefull papers will be published in book form a few months after theconference.In addition to the invited lectures the organizing committee hasreceived an unexpectedly large number of contributed papers. Only about30 of these papers can be presented orally. The other papers will beintroduced by the invited speakers and will be open for discussionthereafter. Nevertheless, $\underline{all}$ contributed papers accepted have beenreproduced in this pre-conference report and will be distributed tothe conference participants before the beginning of the conference.This procedure is hoped to give a basis for fruitful discussions andindividual scientific contacts at the meeting. Reproduction directlyfrom the as-received manuscripts has been employed to assure earlydistribution of this report
