This book is intended to be a reference text on hydrostatic extru sion, a multidisciplinary technology involving the forming process of materials, tribology, high pressure engineering and so forth. Until now only one book bearing the title of hydrostatic extrusion, by Prof. Alexander and Dr. Lengyel, has been published since 1971. Although there are chapters on hydrostatic extrusion in such books as THE MECHANICAL BEHAVIOUR OF MATERIALS UNDER PRESSURE edited by Dr. Pugh, METAL FORMING by Prof. Avitzur and HIGH PRESSURE TECHNOLOGY by Drs. Spain and Paauwe, it is regrettable that no up~to-date reference books on hydro static extrusion are available. As is well known, hydrostatic extrusion is a nearly-ideal lubricated extrusion. Its advantages have been demonstrated by laboratory research in the past two decades, yet many manufacturers, however, still hesitate to adopt the technology in their plants. Their hesitation is certainly due to the lack of exact information on the process and its equipment and also to 'their unfamiliarity with the actual method of operation. In order to provide a useful introduction to the subject for engi neers who work in industries which plan to employ this technique and also to give exact and reliable information on the durability and perfo- ance of production facilities, as well as the capabilities of the process and the properties of extruded products, we decided to publish this book. Starting with theories and computational methods, the processes of cold, warm and hot hydrostatic extrusion are described by experts in their respective fields.

High pressure technology is used so extensively that it is almost impossible to catalogue the manyways in which our lives are enhanced by it. From pneumatic tires and household water supplies tomaterials such as crystals, plastics, and even synthetic diamond, there are countless materialsfabricated or shaped using high pressure technology. High Pressure Technology (in two volumes)presents the most up-to-date information available on the main features of this broad technology andthe processes which utilize it.Volume I: Equipment Design, Materials, and Properties covers three broad areas: the general operationof high pressure systems, including standard operating procedures and safety codes and measures;the technology of high pressure systems, such as components, vessel design, and materials of construction;and applied science at high pressure, including the properties of fluids and solids andmechanical properties. Volume II: Applications and Processes covers processes at high pressure andencompasses such topics as: catalytic chemical synthesis; polymerization; phase changes; criticalphenomena; liquefaction of gases; synthesis of single-crystal materials, diamond, and superhardmaterials; isostatic compacting; isostatic hot-pressing; hydrostatic forming of metals; hydraulic cutting;and applications of shock techniques.Written by recognized authorities in industry, government laboratories, and universities, High PressureTechnology is essential reading for the industrial practitioner, high pressure engineer, and researchscientist. In addition, it is a valuable textbook for students in mechanical, chemical, and materialsengineering courses.
