Abstract

During the traditional process of texture testing, the sample to be tested must be flat. Generally, it is quite complicated and difficult to prepare the texture sample for the x-ray diffraction examination since it usually adopts time-consuming corrosion flattening or slice sticking for tubing. In this work, a new method is proposed to measure the texture of curved tube directly by using Eulerian Cradle installed on the x-ray diffractometer. This nondestructive method is favorable for a special defocusing correction sample composed of pure Ti powders with the same curvature radius as that of the tested Ti alloy tubing, and can be used to correct the strength loss caused by the elongated x-ray spot during the tube testing. It is verified that this nondestructive testing method is valid and feasible as compared to the traditional corrosion flattening method of tubing texture measurement. Moreover, this nondestructive testing method is highly effective, more accurate, and time-saving, which can be used for the rapid texture measurement for Ti alloy tubes.
