The technique of electron microscopic observations was applied to slightly work-hardened aluminum in order to define the nature of the phenomena occurring for degrees of work-hardening very close to the critical work- hardening. it was shown that recrystallization after cold-working of several per cent is connected to the fragmentation of the grains in blocks of a micron during the working. For coldworking of one per cent, there is no formation of blocks. The recrystalllzation does not occur whatever the temperature of thermal treatment. In these conditions the dislocations cannot be eliminated completely by annealing. At higher temperature they combine to form the polygonized state. The formation of boundaries which demarcate this sub-structure was observed. (J.S.R.)
