Enhanced work hardening of the phases in the lamellar microstructure has been cited as an explanation for the lower minimum creep rates of a two-phase TiAl/Ti{sub 3}Al lamellar alloy compared with the minimum creep rates of the individual TiAl and Ti{sub 3}Al single-phase alloys tested between 980 K and 1,130 K. This proposition is confirmed by TEM observations. Thermal and thermomechanical exposure result in the microstructural evolution, which increases the minimum creep rate ({dot {var_epsilon}}{sub min}) of the lamellar alloy. The effect of microstructural evolution on {dot {var_epsilon}}{sub min} will be discussed in the present paper.
