Constitutive analysis for hot working of 2099 aluminum-lithium (Al-Li) alloy was carried out employing friction and temperature corrected flow curves from isothermal hot compression test; in a wide range of temperatures 300~500°C; at strain rates 0.001~10 s-1 and strains 0.1~0.7. The effects of temperature and strain rate on hot deformation behavior were represented in terms of a hyperbolic sine type Zener-Holloman (Z) parameter equation. The influence of strain was incorporated in the constitutive analysis by considering the effect of strain on material constants. Consequently; a model to predict the high-temperature flow behavior of 2099 Al-Li alloy has been established. The true stress-true strain curves predicted by the developed model are in good agreement with the experiment results throughout the deformation conditions except at 300°C in 10 s-1.
