利用分离式Hopkinson压杆试验装置,对具有不同织构特征的TC4合金试样进行动态压缩试验,分析织构特征对钛合金轧板各方向动态力学性能的影响.结果表明,900℃轧制板材的主织构为{1219｝ <12391>±30°RD,织构强度为10.557,在(φ)1=15°时出现峰值,有一定的织构分散,其中晶面{1219}平行板材的轧面,与基面｛0001｝夹角26.6°,晶向由〈1010〉向<6331〉方向漫散；950℃轧板的主织构为{1219｝〈5321〉±20° RD,织构类型与900℃轧板相似,但织构强度为6.387,相对900℃轧板较弱,晶向由〈7341〉向〈4311〉方向漫散,在(φ)1 =35°出现峰值；1050℃轧制板材的主织构为{1219｝〈 1010〉,织构比较集中,织构强度为15.333,晶向〈10l0〉平行板材的轧向,与c轴为90°夹角.950℃轧制的TC4板材,织构强度较弱,其轧向(RD)、横向(TD)、法向(ND)的动态流变应力和动态均匀塑性应变差别不明显.900℃和1050℃轧制的TC4板材,由于织构强度较高,轧板存在明显的各向异性:TD方向的动态流变应力最高,ND次之,RD最低；RD方向的动态均匀塑性应变最大,ND次之,TD最小.
