摘　　要：采用X射线衍射法测定了TA34钛合金管材经不同Q值冷轧后的宏观形变织构和退火织构,分析了冷轧Q值对管材织构、工艺性能和室温力学性能的影响。结果表明:冷轧Q值对管材的塑性影响不大;冷轧TA34钛合金管材形变织构和退火织构的总体类型相同,均为轴向<1010>织构;提高冷轧Q值会使完全再结晶退火后的TA34钛合金管坯产生周向织构,有助于提高成品管材的压扁工艺性能。The macro-deformation texture and annealing texture of TA34 titanium alloy tubes after cold rolling with different Q ratios were measured by X-ray diffraction.The effects of cold rolling Q ratio on the tube texture,processing properties and room temperature mechanical properties were studied.The results show that the cold rolling Q ratio has little effect on the plasticity of the tube;the main types of deformation texture and annealing texture of cold rolled TA34 titanium alloy tubes are similar,both of which are axial<1010>texture;it is obvious to note that increasing the Q ratio produces an increase concentration of basal plane normal to the transverse direction of tubes after complete recrystallization annealing,which is helpful to improve the flattening process performance of finished tube.
