“…Although several EBSD approaches for partitioning of the recrystallized and partially recrystallized phases (e.g. [9][10][11][12]) have been proposed recently, the problem is not trivial. Thus, the applicability of the various methods for the present work is discussed in this section.…”

“…Another EBSD approach is based on the idea that recrystallized grains should have a low orientation-spread [10][11][12]. In this case, EBSD software systematically measures variations of crystallographic orientation within grains.…”

“…Such a modern investigation is facilitated by the application of EBSD with its very sophisticated microstructure analysis capabilities. In this regard, several EBSD approaches have been recently applied for detection and quantification of the recrystallized phase in a partially recrystallized material [e.g., [9][10][11][12]. The objective of the present work was to apply these advanced EBSD techniques to gain further insight into the room-temperature annealing behavior of cryogenically rolled copper.…”

“…each grain must have at least two points with a certain crystallographic direction. The volume portion of dynamic recrystallization that had occurred was calculated with the use of data on the mean misorientation of the lattice inside a grain  mid and the critical misorientation angle  max [47]. In [45] a technique for calculating  max was proposed, and its value for the AMg6 alloy was found to be 1.3.…”

The paper proposes a model of strain resistance of alloy under high-temperature deformation. The model describes hardening of alloy due to the increase of dislocation density, as well as the barrier effect of blocking free dislocations, boundaries of grains and subgrains by dispersoids. The model also takes into account the softening processes associated with the recovery and dynamic recrystallization. The model has been tested on the rheological behavior of an Al-Mg alloy named AMg6 at temperatures of 400 and 500 ºC in the range of strain rates from 5 to 25 s -1 . It was found in this temperature -strain rate range that the curve of strain resistance of the AMg6 alloy consists of several portions. First there is hardening of the material, then there is material softening, which is again replaced by hardening of the material. With the use of the electron backscatter diffraction technique and transmission electron microscopy, it was found that the main process of softening at investigated temperatures is dynamic recrystallization. The appearance of the second portion of hardening on the strain resistance curve is the inhibition of dynamic recrystallization, as well as manifestation of the barrier effect of blocking free dislocations, grain and subgrain boundaries by dispersoids.
