Hausner's handbook covers the entire field of powder metallurgy with its various branches and refinements, while at the same time remaining within the bounds of manageable size and readability. It is a concise presentation concentrating on graphical presentations and tables to explain basic relationships between the principles and technology of powder metallurgy.

This book is a valuable guide not only for students and teachers but also for the practical powder metallurgists involved in research, development and production of P/M parts and compounds.

Five years ago, the worldwide powder metallurgy fraternity gathered in New York City to attend the first international conference devoted entirely to powder metal lurgy to take place in the United States. It was a tentative venture, entered into by the sponsors with no idea as to whether it would fail or succeed. The only assurances we had were that the metal-powder producing and consuming industries were rapidly expanding and that powder metallurgy was truly becoming one of the international sciences. The 1960 Conference was successful not only in terms of attendance and interest, but also in terms of knowledge gained. The literature had been enriched by the contributions of its participants to foster and encourage this type of world wide exchange. Thus, another such conference was held in 1965-expanded in scope and supplemented by an exhibition of the latest advances in raw materials, processing equipment, and finished products of powder metallurgy. On behalf of the Conference sponsors-the Metal Powder Industries Federa tion, the American Powder Metallurgy Institute, and the Metallurgical Society of AIME-I thank all those who participated and who helped make the 1965 Interna tional Powder Metallurgy Conference a rewarding experience and memorable event in our industry's history. Support of the National Science Foundation, which made it possible for several speakers from abroad to participate in the program, is gratefully acknowledged.

Aluminum P/M parts can be production sintered in various types of furnaces and atmospheres. Selection of sintering furnace depends upon economic considerations and production rates desired. Batch furnaces have lowest investment costs and are adequate for low to medium production whereas continuous furnaces are more costly but provide higher production rates. strong, well-sintered P/M parts can be obtained in atmos pheres of nitrogen, dissociated ammonia and in vacuum. Atmos phere selection depends upon facilities available within individual plants plus property requirements. Highest strengths are produced in nitrogen followed by vacuum and dissociated ammonia. Repro ducible dimensions can be achieved with proper attention to com pact density, sintering temperature, dew point and atmosphere. REFERENCES 1. J. H. Dudas and W. A.

Powder metallurgy literature in the English language includes a large number of books and several thousand articles in various journals. The rate of growth of this literature increases from year to year. It covers well the whole field of powder metallurg- materials, processes and products - with two exceptions: friction and antifriction branches of powder metallurgy. This lack of information has nothing to do with scientific or technical considerations, and definitely has nothing to do with lack of initiative in the development of these materials. The industry concerned with the production of friction and antifriction materials is continually developing new products and techniques and produc tion is steadily growing. However, most companies working on these materials regard their experiences and new advancements as "proprietary" and, for competitive reasons, are not interested in publishing in the technical literature except for very perfunctory and usually highly commercial papers. Very little work on fric tion and antifriction materials is going on in independent labora tories and university laboratories, although fundamental studies in this field offer very interesting aspects.
