Abstract
In the present progress report advances in those metal deformation processes that are characterized by a substantial change in workpiece thickness are discussed. The first topic is the rolling of flat products and of shapes, both hot and cold. Because of its vastness, the theme is selectively handled, with emphasis on production facilities and practices, automation, and a brief review of theoretical developments. The second section is on improvements in tube piercing and reducing methods with emphasis on improved quality and productivity. In the third section the first comprehensive coverage of advances in impression- and closeddie forging in this series is given, and emphasis is placed on the understanding gained in relation to material flow, the application of computers to process design, and interactions witL. dies and forging equipment. Finally, advances in the practice and theory of wire drawing are discussed, including the effects of input material and process conditions on quality. The processes of hot and cold extrusion, conspicuous by their absence, are to be the subject of separate reviews.
