TiAI-based alloys with two-phase structure, Le gamma plus alpha 2, offer the best balance of creep, ductility and strength. However, there is a distinct difference in thermal expansion coefficients between the two phases, which can be as large as 30-40% at the potential service temperatures 600-800C. This will lead to the generation of stress at the interfaces. Under cooling and heating cycles, dislocations are created. This proposal aims to assess the influence of the thertnallyinduced stresses on the performance of TiAl-based alloys by carrying out a number of tests in which different stresses are imposed during a range of thermal cycles for which the frequency and temperature ranges are altered. It is particularly important that the influence of thermal cycling is understood now that these alloys are being introduced commercially.
