A complex two phase {gamma}-TiAl alloy, Ti-47Al-1Cr-1Mn-2Ta-0.2Si (at.%) in a fully lamellar condition, has been creep tested at a stress of 200 MPa and a temperature of 700 C. This simulates the in-service operating conditions for several potential gas turbine aero engine applications where creep resistance is a design limiting material property. The results indicate that reduction in lamellae thickness and avoidance of feathery type microstructures contribute to improved creep resistance.
