| 摘 要： | 研究了单道次皮尔格轧制过程中Ti-2Al-2.5Zr材料的变形行为和织构的演变规律。结果表明，在轧制过程中，｛102｝孪晶和柱面滑移是最容易被激活的2种变形模式，｛102｝孪晶的产生使得晶粒在轴向上的位向从<100>转向<110>。并且，在不同瞬时Q值和等效应变量下，滑移和孪生导致｛0001｝极图中最大极密度点在切向上发生变化。

| Abstract: | The evolution of deformation behavior and microtexture in one pass cold Pilgering process was investigated. Results show that during cold Pilgering, the {102} tensile twin and prismatic slip are the two modes that are most easily activated. The activated {102} tensile twins cause the grain orientation changes in axial directions, which changes from <100> to <110>. The maximum intensity point of {0001} pole figure changes along the TD, which is attributed to twinning and slip under different transient Q-value and equivalent plastic strain. |
