Abstract
The high temperature flow behavior of 7A52 aluminum alloy during high temperature plastic deformation was studied by isothermal compression of cylindrical specimens using Gleeble-1500 thermal simulation machine.The results show that the flow stress decreases with the increase of deformation temperature and increases with the increase of strain rate.The flow stress equation of 7A52 alloy during temperature deformation can be represented by a formula.The better hot deformation processing can be designed at 400℃-420℃.
