【 摘 要 】

The microstructure and the texture evolutions of partly recrystallized samples of pure Al and the Al-1%wt. Mn alloy have been characterized by a high resolution SEM/EBSD. The single crystals of the Goss{110}<001> and brass{110}<112> orientations, stable in the plane strain compression, were deformed in a channel-die up to 60% to develop a homogeneous structure composed of two sets of symmetrical primary microbands and then shortly annealed. It is documented that the orientations of the initial nucleus were scattered but not accidental. The disorientation axes in the orientation relationship across the recrystallization front usually coincide with one of the <112>, <221>, <102> or <111> crystallographic directions and were rather rarely close to the <110> or <001> directions. The disorientation axis of the <111>- type is only one of the few most often observed.
