On the Local Distribution of the Strain in Plastically Deformed Aluminium Crystals (2nd Report). Changes due to Heating

Masaichi Yamamoto, Satohiro Hayami and Zenji Nishiyama


Abstract:

Using plastically deformed aluminium crystals, changes in distribution of the strain during heating were investigated with X-ray diffraction microscopy (Berg-Barrett method), in order to clarify the polygonization and recrystallization process. The X-ray micrographs locally showed recovery aspects and sub-grain formation. In the crystal which showed deformation bands the sub-grains formed with recovery are parallel to the bands. In case the deformation bands did not appear the subgrains are nearly parallel to slip bands.
