Verlagsdienstleistungen GmbH, Weinheim Printing: Druckhaus Darmstadt GmbH, Darmstadt Bookbinding: Buchbinderei Schaumann GmbH, Darmstadt Printed in the Federal Republic of Germany V Introduction This book covers the papers which were presented either orally or as posters during the 8th In- ternational Conference on Shot Peening held in Garmisch-Partenkirchen, Germany, September 16-20, 2002. Shot peening has been proved to be a powerful instrument in enhancing the resistance of ma- terials to various kinds of stress-induced damage, particularly against damage due to cyclic loa- ding in air or in aggressive environments. As shot peening can be used for a wide variety of structural components irrespective of shape and dimensions, the number of shot peening applications in many industrial branches is increa- sing. The use of peen forming as a technique to form large metal parts into complicated shapes is also increasing, particularly in the aerospace industry. ICSP8 was the eighth in a series of international conferences (1981 Paris, 1984 Chicago, 1987 Garmisch-Partenkirchen, 1990 Tokyo, 1993 Oxford, 1996 San Francisco, 1999 Warsaw) and offered scientists and engineers a unique opportunity to update their knowledge. This highly successful conference attracted more than 200 participants from 18 countries. Of the more than 100 abstracts submitted, 71 papers were finally accepted for publication by the International Scientific Committee on Shot Peening (ISCSP). I would like to thank those mem- bers of the ISCSP who have been willing to review the submitted manuscripts in order to impro- ve the quality of the proceedings. The contributions are arranged in the book according to the conference topics, i.e., Applicati- ons, Techniques and Controlling, Surface Layer Properties, Peen Forming, Corrosion and Fret- ting, Fatigue of Fe- and Ni-based Alloys, Fatigue of Light-Weight Alloys, Alternative Mechanical Surface Treatments and Modeling.
