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 high-temperature deformation behavior of Q345 steel is detected by a Gleeble-3800 thermal simulator. The Arrhenius constitutive equation for high-temperature flow stress and the dynamic recrystallization model are constructed. With the secondary development technology, customized modifications are made on existing Deform-3D software. The constructed constitutive model and dynamic recrystallization model are embedded into Deform-3D to realize the secondary development of Deform-3D. The grain size and volume percentage distribution of dynamic recrystallization are obtained by simulating the shear connection process at high temperature and high speed. The results show that the constitutive equation and the dynamic recrystallization model constructed in this paper can be used to predict the evolution of the microstructure. The difference between the prediction results and the experimental data is about 3%. The accuracy of Arrhenius constitutive equation, dynamic recrystallization model and the feasibility of software secondary development are verified.
