Abstract：Hot compression deformation test of 6061 aluminum alloy was performed on Gleeble‐3500 thermal mechanical simulator at the deformation temperature range of 300~450 ℃ ,the strain rate range of 0 .01~10/s and the height reduction of 60% .The errors in experimental data caused by friction were cor‐rected and the flow behavior of 6061 aluminum alloy at elevated temperature under different hot deforma‐tion conditions w as investigated .In addition ,by applying the established constitutive equation into the fi‐nite element analysis software DEFORM‐3D and creating user‐defined material properties ,the hot compres‐sion process of 6061 aluminum alloy w as simulated .T he results show that 6061 aluminum alloy has a posi‐tive strain rate sensitivity under the given experimental conditions ,the flow stress decreases with increasing deformation temperature and increases with increasing the strain rate ,which can be described by Zener‐Hollomon parameter in the hyperbolic sine equation based on modified Arrhenius model with the hot de‐formation activation energy of 314 .304 kJ/mol .During compression at elevated temperatures ,the deforma‐tion of 6061 aluminum alloy is inhomogeneous ,the largest deformation occurs at the central of specimen and the value of effective stress obtained from finite element simulation is very close to the obtained experi‐mental value .
