Abstract An investigation was conducted of the relationship between the orientations of recrystallized grains, the deformation amount and the tensile temperature with the tapered single crystals of A1 and Cu. In A1 single crystals, the orientations of recrystallized grains became concentrated when plastic deformation fully entered into the third work hardening stage during tensile test at—78—300℃, and had a crystallographic relationship with the deformed parent in rotating around the [111] about 30—50°, but it was rand random after tensile test at—196℃. In Cu single crystals, the orientations of recrystallized grains were also radom after tensile test at 20—400℃.In consideration of the difference of stacking fault energy in AI and Cu and in A1 with decreasing temperature, the deformed structure in third work hardening stage would be different. From the point of view that the nucleation of recrystallization occurred by the growth of subgrains of large difference in orientation with surrounding matrix and of taking the lead during the recovery process, the different relationship between the orientations of recrystallized grains and the deformed parent can be explained.
