It is shown that in the extruded Al6082-T6 alloy under consideration, twin grain boundaries and other highly misoriented grain interfaces, which constitute significant barriers to plastic slip, provide internal domains in the material where initiation of fatigue damage is more likely to occur than at the stress concentrations which are due to the surface roughness.
Deformation resulted in a macroscopic subdivision across the specimen thickness into three types of region – matrix regions, transition regions, and a central region consisting of two sharply alternating, highly misoriented, orientations.
Upon straining, dense dislocation walls were developed in ferrite grains, which evolved gradually into sub-boundaries and highly misoriented grain boundaries (GB) at increasing strains, leading to grain refinement of the ferrite.
In the subsurface layer of the SMAT Cu samples with low strain rates, grains are refined via formation of dislocation cells (DCs), transformation of DC walls into sub-boundaries with small misorientations, and evolution of sub-boundaries into highly misoriented grain boundaries.
Although E-caddCR4h-expressing GSCs were well maintained, their centrosome was highly misoriented (∼35% misoriented centrosomes, Figure 2A right panel, B, D).
In the absence of Baz, centrosome is highly misoriented.
If the COC is intact, GSCs with misoriented centrosomes would halt cell cycle progression prior to mitotic entry, resulting in a low frequency of spindle misorientation, even if the centrosomes are highly misoriented.
Maybe they're more highly motivated".
These changes have rewarded acrobatics more highly.
Only French Polynesia is more highly prized.
