Abstract: 2195 aluminum alloy with high strength/low density is the preferred material for weight reduction of aerospace components. Static recrystallization often occurs during the medium temperature deformation of 2195 aluminum alloy, and static recrystallized grains have an important impact on the final mechanical properties of materials. Therefore, in this work, the effects of different deformation temperatures (160—240 ℃) and holding time (0—30 s) on the static recrystallization behavior were studied by hot compression test, hardness test, EBSD and XRD testing techniques. The dislocation evolution law at different deformation temperatures was analyzed and the mechanism of static recrystallization evolution was explored. The results show that when the grains with GOS value (average grain orientation angle value) less than or equal to 0.4° are recrystallized grains. When the deformation temperature is 160—240 ℃, the strain rate is 0.01 s-1 and the deformation degree is 30%, the size of static recrystallized grains gradually increases with the extension of holding time t (t<20 s). However, when the deformation temperature is 240 ℃, the static recrystallized grains do not increase with the extension of holding time, but only grow up slightly. In the static holding process, 160 ℃ deformation materials is faster than that of 200 ℃ and it is easier to form fine static recrystallized grains. Based on the above rules, the static recrystallization kinetic model of 2195 aluminum alloy during the medium temperature deformation process was established, which has good prediction effect. The results of this study have important theoretical value and practical significance for optimizing parameters of 2195 aluminum alloy during thermal deformation process and heat treatment.
