Abstract：

In order to improve the thermal workability of 6061+ Er aluminum alloy, the microstructure of 6061+ Er aluminum alloy and its thermal deformation behavior under the deformation temperature of 375-500 ℃ and the strain rate of 0.001-10 s-1 were analyzed by scanning electron microscope, transmission electron microscope and thermal simulation test machine Gleeble-3800. The results show that there are micron primary Al3Er phase and nano secondary Al3Er phase with dispersion strengthening effect in forged 6061+Er aluminum alloy. The constitutive equation of rheology stress during the thermal compression deformation process for 6061+Er aluminum alloy is established, and the error between the calculated value of rheology stress and the measured value of peak true stress under the strain rate of 0.001-10 s-1 and the deformation temperature of 375-500 ℃ is less than 10%, the accuracy and reliability of the rheology stress constitutive equation are verified. Thus, the suitable thermal processing range of 6061+Er aluminum alloy is that the deformation temperature is 375-400 ℃ and the strain rate is 0.001-0.01 s-1.
