Study on the microstructure of AA6016/AA7050/AA6016 laminated composites based on Murty and Prasad instability criterion
Source abstract
Abstract
In this paper, AA6016/AA7050/AA6016 laminated composites were produced through the single-pass hot compression tests on the Gleeble-3500 thermal simulator. The hot deformation behavior, macrostructure, microstructure evolution and deformation mechanism of AA6016/AA7050/AA6016 laminated composites were studied. The hot processing maps of composites were established based on Murty and Prasad instability criterion. The results showed that composites underwent work hardening under the initial strain and then underwent the dynamic softening process through analyzing the flow stress-strain curves. Two components of composites had different macrostructures, in which AA7050 was drum-shaped while AA6016 was concave-shaped. Compared with the Murty instability criterion, the Prasad instability criterion can more accurately determine the reasonable processing area and instability area of composites, which the reasonable processing parameters were 350–450 °C/0.1–1 s −1. The deformation coordination of composites in the reasonable processing area was better than that in the instability area, which was more conducive to the deformation coordinated of the two components. The deformation mechanism of AA7050 was dynamic recovery (DRV), while AA6016 was continuous dynamic recrystallization (CDRX) during the dynamic softening process.
