Hydrostatic Extrusion e-bog

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.
