Syracuse University and the Army Materials and Mechanics Research Center of Watertown, Massachusetts have conducted the Sagamore Army Materials Research Conference since 1954. In ce1ebration of the 25th Anniversary of this conference, these proceedings are dedicated to the founding members of the Sagamore Conferences. They are Prof. Dr. George Sachs, Dr. James L. Martin, Colonel Benjamin S. Mesik, Dr. Reinier Beeuwkes, Mr. Norman L. Reed and Dr. J. D. Lubahn. This vo1ume, ADVANCES IN METAL PROCESSING, addresses Rapid Solidification Processing, Powder Processing and Conso1idation, We1ding and Joining, Thermal and. Mechanica1 Processing, Meta1 Removal and Process Mode1ing. The dedicated assistance of Mr. Joseph M. Bernier of the Army Materials and Mechanics Research Center and He1en Brown DeMascio of Syracuse University throughout the stages of the conference p1anning and fina11y the pub1ication of this book is deep1y appreciated.
