FERROUS METALS - BIBLIOGRAPHY - INDEX -Excerpt from Book (short): Preface - The impact or cold extrusion of metals is a chipless machining process that can greatly reduce costs of material and labor if properly applied. Within certain limitations in shape, some parts can be produced by this process that often require only trimming to length. On others, the secondary operations are reduced greatly over those required for several of the competing processes. Finally, certain components can be made that can be produced by no other method. Impact extrusion can be employed for the production of parts from a wide range of metallic materials. In commercial production at present are components produced from aluminum, copper, lead, magnesium, tin, zinc and their alloys and various steels. In the development stage are parts produced from less common metals, such as titanium and molybdenum. The aim of this book is to present a coordinated description of impact extrusion. Its purpose is to present the information required by an engineer to determine whether the process is applicable to his products, and to assist the metallurgist in selecting the metal to be used. The book is based on personal experience, talks, and correspondence with producers of components, and a search of the free-world technical literature. It is divided into two parts. The first deals with the underlying principles and the characteristics of the process; the second, with the metals being extruded and the products.
