Temperature Deformation

The current characterization of the rheological behavior during high temperature deformation in AA7075 is presented. The prevailing understanding in the literature is limited to the consideration of process parameters in isolation of microstructural features and the dynamics at the deformation zone in relation to geometry of the die tool and frictional conditions. Multiplicity of phenomena such as dynamic recovery (DRV), discontinuous dynamic recrystallization (DDRX), continuous dynamic recrystallization (CDRX), and geometric dynamic recrystallization (GDRX); are reported to dictates the dynamics in play during high temperature deformation of the alloy. Therefore, a need to appropriately characterize the flow behavior in AA7075 alloy during high temperature thermo mechanical processing that would involve an integrative study of concerned process parameters, metallurgical features and conditions at the deformation zone is imperative in order to achieve wholesome understanding of the flow behavior in AA7075 aluminum alloy during high temperature deformation.

The variation of the flow stress and the microstructural evolution during hot deformation at different test temperatures and strain-rates are studied. During hot deformation, dynamical recrystallization did not occur completely; after annealing at 523K, microstructural changes due to static recrystallization and small grain sizes of several micrometers and fine nanometer-precipitates can be attained. The stress exponent (n) and the activation energy (Q) for high temperature deformation have been evaluated and the deformation mechanisms at different temperature have also been discussed.
