Opis

This publication addresses the various advances in materials and process technologies required for superplastic forming to enter mass production environments such as the automotive industry, where fast cycle time is a key requirement. The proceedings focus on the forming of light alloys at more rapid rates and lower temperatures. Results of advanced R&D efforts from both industrial and university laboratories are presented. Scientists and engineers employed at automotive and aerospace manufacturing companies, as well as researchers based at universities, will find this volume particularly useful. From 2004 TMS Annual Meeting which was held in Charlotte, North Carolina, March 14-18, 2004
