Texture Development In Titanium Aluminide Alloys

texture.jpg (19808 bytes)Problem: A Cooperative Research and Development Agreement (CRADA) was developed to investigate texture development in gamma titanium aluminide alloys during hot working. General Electric Company (GE) wanted to know if these materials could be used in jet engine structures.

Solution: GE and the Air Force Research Laboratory (AFRL) under a CRADA extruded, forged, and rolled gamma titanium aluminide to create various crystallographic textures. Textured alloys often have better properties than alloys without such textures.

Benefits:

  • General Electric will benefit by the use of techniques developed under this CRADA in its existing turbine engine business.
  • The Air Force Research Laboratory will benefit by development of these new techniques for use in military jets and other U.S. Government components.

Current Status:

  • This CRADA is complete.
  • Wrought gamma titanium aluminide alloys have been successfully tested in jet engines and are now being considered for other applications such as skins for reusable launch vehicles.
If you have any questions about this Cooperative Research and Development Agreement or are interested in getting more information about technology transfer and CRADA projects, please contact Jim Singer at Wright Technology Network (937) 253-0217 or CRADA@wtn.org
