摘要：

The textures of homemade cold rolled Ti-3Al-2.5V alloy tubes with the diameter of 6 mm were investigated. The textures were measured by means of pole figure technique of X-ray diffraction. Meanwhile, the components and intensity of textures of the imported commercially aviational tubes with the same diameter were measured and compared to those of the homemade tubes. The difficulty of the inable revision of the shape effect on X-ray diffraction intensity was solved by the method of thinning and flattening, resulting in realizing of the accurate measurement of the tube texture. The experimental results show that the textures type of domestic and imported tubes are the similar. Main type of texture is that the included angle between the crystal orientation [0002] and radial direction of tube is 24°, meanwhile the crystal orientation [101¯0] is parallel to the axial direction of tubes. However, the texture intensity difference between domestic and imported tubes is remarkable. The quantitative value of the latter is twice as much as that of the former. Thus inceasing of the texture intensity and reducing of dispersion degree are an important factor of improving the properties of domestic tubes.
