TiAl-base, gamma titanium aluminide alloys exhibit high temperature mechanical properties that make them attractive candidates for a variety of applications in advanced turbine engines. This paper presents an overview of the capability of available gamma titanium aluminide alloys in both cast and wrought forms. Emphasis is given to cyclic properties that will govern component life under anticipated usage in gas turbine engines. The roles of fatigue crack initiation and growth are examined, and approaches for life prediction are discussed. An attempt is made to assess the strengths and limitations of these materials with respect to application requirements.
