主　　题：Magnesium alloy Alternating extrusion Texture Recrystallization Grain orientation 

摘      要：The interactive alternating forward extrusion(AFE) method can realize the change of texture type and the weakening of texture strength.Taking AZ31 magnesium alloy as an example, the texture evolution of interactive AFE was studied. The results show that all kinds of dynamic recrystallization(DRX) behaviors can weaken the texture to vary degrees. The weakening effect of twinning-induced recrystallization(TDRX)behavior was particularly significant. During the interactive AFE process, the c-axis of most grains rotated under the external force, and tended to be 90° angle with the ED direction, forming a stable fiber texture. In addition, with the increase of loading passes, the starting of {0001} basal slip system became more and more difficult. The(10–10) texture formed by {10–10} prismatic slip system after sixth passes was the main texture type. With the increase of forming temperature, the starting ability of {10–10} prismatic slip systems increased, and the(10–10) texture formed by prismatic slip system above 623 K dominated.
