Abstract:The formation of recrystallization texture with rolling orientation (e g theRtexture) and its influencing factors in a pure Al-1.3%Mn alloy were investigated by means of X-ray texture analysis and particularly local orientation measurements based on EBSD in SEM and MBED in TEM. The results show that this texture component is caused by the grains formed at grain boundaries through SIBM mechanism and its formation is favored by Mn atoms in solution, large initial grain size and low annealing temperature. The grains formed in this way are mainlyB/Roriented and their growth is inferior to that of cube grains. The reason for the formation of such texture component is attributed to the differences in misorientations of different matrices, the deformation behavior relates to initial grain size and the Mn atoms in solution.
Key words: recrystallization texture AlMn ODF
