Opis

Titanium and titanium alloys are used in many demanding applications in aerospace and terrestrial systems because of their excellent combination of mechanical properties and corrosion resistance. However, high costs resulting from an energy-intensive extraction process and complex fabrication sequence excludes titanium alloys from many applications. This proceedings volume will address all aspects of potential cost reduction of titanium alloys, covering such segments of titanium technology as extraction, creative melting including cold-hearth approaches, near-net-shape techniques, processing and fabrication advances, high-speed machining and knowledge-based processing with emphasis on computer-aided approaches, improved process control, and creative designs. This volume will be of widespread interest to materials scientists and engineers working in the aerospace, automobile, chemical processing, medical, and consumer industries. From 2004 TMS Annual Meeting to be held in Charlotte, North Carolina, March 14-18, 2004. An errata document for the volume is available for complimentary download.
