Gamma titanium aluminide is a material essential for meeting military and civil engine performance targets in the future and potentially it could be used throughout the engine from compressor to combustor to turbine. The current alloy being used within Rolls‐Royce is the established Ti‐45‐2‐2‐XD. This is competing for lower temperature applications such as stators and structural Cited by:

For over a decade in the s, the attractive properties of titanium aluminides were outweighed by difficulties encountered in processing and machining at room temperature. Advances in gamma titanium aluminides and their. The history of GE’s efforts to utilize gamma titanium aluminides (TiAl) is an excellent case study of how the development process evolves. 1 In this case, the advanced material went through the traditional materials development process, but found application in a commercial engine rather than in the originally targeted military systems. Realizing the benefits of gamma TiAl has been the goal.

    A method for producing fine-grained lamellar microstructures in powder metallurgy (P/M) and wrought gamma titanium aluminides comprises the steps of: (a) a cyclic heat treatment at a maximum temperature in the range of about 10° C. above to about 10° C. below the alpha-transus temperature (α) of the alloy, and (b) a secondary heat treatment of thus cyclically heat treated alloy at a Cited by:   A study was undertaken to determine the feasibility of the AWJ process for controlled depth milling of gamma Titanium Aluminide tiles. It was demonstrated that milling can be accomplished to mm accuracy. To overcome undercutting near rib roots, the jet was clock-angled at about 15 deg to the vertical every set of by: 9.
