摘　　要：针对增材制造钛合金的组织特点,采用EBSD以及XRD的方法对增材制造TC11合金进行了织构分析,探讨TC11合金从微米级微观织构到厘米级宏观织构的变化规律,分析了EBSD扫描面积大小对织构分析结果的影响。结果表明,采用大面积EBSD拼接扫描的织构分析结果与XRD宏观分析结果一致。TC11合金β相具有<001>∥沉积方向的丝织构及弱(001)[010]板织构,α相的主织构为<160 16 19>∥[001]、<2110>∥[001]丝织构。According to the microstructure characteristics of laser additive manufactured titanium alloy, the texture of laser additive manufactured TC11 alloy was investigated by EBSD and XRD, from micron scale to centimeter scale, and the effect of scanning area of EBSD on the texture was analyzed. The results show that the textures tested by EBSD are consistent with the results of XRD. The β phase of TC11 alloy shows the <001> fiber texture parallel to the building direction and weaker(001)[ 0 10 ] plate texture, and the α phase exhibits two fiber textures, <160 1619>∥[001] and < 2 1 10 >∥[001].
