Deformation Behaviour of Aluminium Macrocrystals in the Grain Boundary Region

摘要: Lattice distortions of deformed aluminium macrocrystals were observed by Electron-microprobe-Kossel techniques. Grain boundary effects due to deformation appeared in various ways such as extraordinary separation and branching Kossel lines, intergranular rotation the grains pseudo-Kossel X-ray diffraction patterns obtained from grain regions specimens. Such peculiar attributed effect local slipping induced active slip systems neighbouring crystals. By interpretation these orientation relationships between grains, it was found that towards direction plane crystals, or a type stress along planes It also recognised at an early stage stressing, bands produced region result effect.
