- The hot deformation behavior of Al-Zn-Mg aluminum alloy was investigated by means of compression tests and Finite Element analysis method in the temperature and strain rate ranges of 350oC to 500oC and 0.1s-1 to 0.4s-1, respectively. The load-displacement data and the maximal cross section area S predicted by finite element method (FEM) were in good agreement with those from experiment. As expected, the flow stress was increased with strain rate, and decreased with deforming temperature. The flow stress of the Al-Zn-Mg aluminum alloy during hot compression deformation can be described by using Zener-Hollomon parameter, and it confirmed that the Zener-Hollomon parameters during hot deformation can be determined by simple compression testing in conjunction with validated numerical modeling. Finally, the relation of maximal cross section area S of barreling profile and strain during compression processing was established.
