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,■孪晶和柱面滑移是最容易被激活的2种变形模式,■孪晶的产生使得晶粒在轴向上的位向从■转向■。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。
The evolution of deformation behavior and microtexture in one pass cold Pilgering process was investigated.Results show that during cold Pilgering,the■tensile twin and prismatic slip are the two modes that are most easily activated.The activated■tensile twins cause the grain orientation changes in axial directions,which changes from■to■.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.
