“…6 and 7 for R and R2 specimens, respectively. TF value represents the orientation hardness [22]; the grains with a lower TF value were associated with lower yield strength and could be deformed at lower stresses. In both R and R2 specimens, at the low strains of about 0.1, a random distribution of low and high TF value grains was observable.…”

“…In addition, the morphology of orange peel resulting from anisotropy of tube hydroforming is inconsistent with the anisotropy of plastic strain inside grains. By analysis of the angle misorientation in the studied sample area using EBSD data, the crystallographic orientation of all grains can be determined, which makes possible to calculate the misorientation between neighboring grains [3].

“…A common defect of roping or ridging has been extensively investigated by rolling and tensile deformation. More studies have been focused on the origin of surface defects and on quantitative estimation of dependence of associated surface roughening on the spatial gain orientation distribution using the technique of electron backscatter diffraction (EBSD) [3,4]. A clear relationship between roping development and the spatial distribution of the Goss component was identified [6].…”

The occurrence of orange peel in 6xxx alloy tube for automotive application was studied by super depth metallographic microscope and EBSD. The results revealed obvious ups and downs morphology at the surface after tube hydroforming. Compared with the undeformed case, more grains existed in the concave areas rather than individual out-of-plane displacement. The influence of surface orange peel on grain boundary morphology, crystal orientation, and texture are discussed. It is concluded, that surface orange peel is controlled by the spatial distribution of grain orientations and grain size through the thickness of the sample.

“…It has also been reported that recrystallization and abnormal grain growth can occur in an Al layer after hot deformation and during subsequent annealing [6]. It has also been observed that roughness can form during deformation of polycrystalline metallic materials with FCC structure or HCP structure due to heterogeneity of plastic deformation [7][8][9]. This phenomenon has also been observed at the interfaces of LMCs produced by rolling [4] and this kind of heterogeneity can cause structural differences during annealing of the LMC.…”

The preparation of the Ti-Al alloys based on intermetallic phases N Kosova, V Sachkov, I Kurzina et al. -Investigation of physical and mechanical properties of coatings based on intermetallics of the Ti-Al system obtained in acetylene environment from vacuum-arc discharge plasma E L Vardanyan, A Yu Nazarov, K N Ramazanov et al. Abstract. A laminated Ti-Al composite has been fabricated by hot compaction and hot rolling of alternate layers of commercial purity Ti and Al sheets with a thickness of 200 μm. The hot compaction temperature was 500˚C and in a following step the composite has been reduced 50% in thickness by hot rolling. The fully consolidated composite has been annealed at 300˚C and 500˚C for different length of time. As a result of the differences in crystal structure and mechanical properties between Ti and Al protrusions and retrusions formed at the interface. A heterogeneous interface has thereby been created. The heterogeneity affected the recovery kinetics of the aluminium phase which at 300˚C was faster near the interface than in the middle of the Al layer. This effect of a heterogeneous interface is of relevance when optimizing the thermomechanical processing of the composite to obtain high strength and formability for application.
