【Abstract】 The influence of different annealing processes on the recrystallization and grain growth behaviors of low voltage electron aluminum foil was investigated using the quantitative texture analysis, EBSD micro orientation analysis, as well as grain size measurement. The corresponding processes were also discussed based on the current recrystallization theory. A recovery process before primary recrystallization will reduce the storage energy as well as the recrystallization driving force drastically, and therefore influence the recrystallization grain size and volume fraction of cube texture systematically. An abnormal grain growth process, connected with strong cube texture in electron aluminum foil, could be induced by certain special annealing treatment, which will decrease the volume fraction of cube texture obviously.更多还原
