Recent Titanium Research and Development in Germany D. Helm, O. Roder MTU Aero Engines, Munich, Germany This paper gives an overview about recent research and development work performed at universities and maj or research facilities as well as at different areas of industry covering the production and application of Titanium alloys in Germany. Examples of research addressing the relationship of microstructure and mechanical properties on conventional Titanium alloys are presented; additionally, investigations on coatings protecting material from erosion will be highlighted. Furthermore, alloying concepts and latest alloy developments focusing on γ-Titanium-Aluminides are shown. On the production side, a review of new developments at Germany’s maj or melting, forging and investment casting facilities is given. Finally, a brief survey is presented about recent development work on Titanium components used in a wide variety of different applications, covering aerospace, aero-engine and automotive industry.
