Relationship between multiple-slipped deformation and recrystallization in< 112 > aluminum single crystal

In order to clarify the relationship between deformation-induced structure and formation of recrystallized grains in multipled slip regions, < 112 > a luminum single crystal was deformed in tension to a strain of 22% at room t emperature and then annealed at certain condition. The results obtained wer e compared with the previous ones of < 111 > and < 001 > single crystals. N o deformation band was observed in < 112 > specimen in addition to < 001 > and < 111 > ones. The misorientations in the whole area of the deformed < 1 12 > specimens were within 5 degrees. More than sixty percent of recrystall ized grains had the < 111 > rotation recrystallized relationship with the d eformed matrix. The stress value at 22% strain and the number of the recrys tallized grains in < 112 > specimen were relatively smaller than those in < 111 > one and larger than those of < 001 > one. The behaviors of deformati on and recrystallization are discussed to be affected strongly by the opera tion of cross slip.
