Owing to the high strength and hardness, the mechanical polishing process usually can not remove the residual strain layer covered with the titanium-alloy specimen; the electropolishing process should be the ideal method for preparation of the Ti-alloy specimen for Electron Back Scatter Diffraction testing. After a mass of trial and error by rectifying some of the parameters from the selected processes, the convenient process for titanium-alloy EBSD specimen preparation was established finally.
