Abstract :
Equal channel angular pressing (ECAP), as one of the most feasible severe plastic deformation (SPD) techniques for industry manufacturing, can produce ultra-fine grained (UFG) structures and improve properties and forming ability of titanium alloys. The basic principle, research development and application of preparing UFG titanium alloys were introduced. The effects of different ECAP factors on microstructure and properties, and the micromechanism of grain refinement were analyzed. Finally, the problems and prospects were discussed.
