WebbSolution for Briefly explain why small-angle grain boundaries are not as effective in interfering with the slip process as are high-angle grain boundaries. Skip to main … WebbIn Section 6, finally, we first explain a simplified model for small angle grain boundaries where we assume rotation by an angle #=2in both half-planes in opposite direction; this problem is somewhat easier to deal with. We furthermore discuss special rotation angles #for which the operators R #are periodic in the y-direction

In the CDRX process, the substructure is almost equiaxed or slightly elongated along RD, then gradually evolves into similar shape of sub-grain and grain.
