Notes:
TEM, Kikuchi diffraction analyses, EBSD, neutron diffraction and hardnessmeasurements have been applied in a study of commercial purity aluminum (AA1200) cold rolledto strains 2 and 4 and afterwards recovered by a heat treatment for 2h at temperatures up to 220 °C.The deformation microstructure is a lamellar structure delineated by dislocation boundaries andhigh angle boundaries ( ) parallel to the rolling plane. The macrotexture is a typical rollingtexture which is composed of individual texture components present as micrometer- andsubmicrometre-sized volumes. In the lamellar structure, correlations have been established betweenmicrostructural parameters and the local texture, showing for example that the density of high angleboundaries and the stored energy vary locally. The local variations affect the annealing behaviors ina way that some regions coarsen faster than others, leading to a recovered structure which isheterogeneous
