How to control the microstructure of titanium alloy bars is important to fabricating high-performance aerial forgings. This paper gives a thorough survey of the manufacturing methods and microstructure control techniques for titanium alloy bars. It summarizes the effects of processing parameters on the mechanisms and laws of microstructure evolution during b working and(a + b) working, including the kinetics and grains size of dynamic recrystallization(DRX) during b deformation and the kinetics and grains size of spheroidization during(a + b) deformation. The trends in microstructure control techniques are presented for fabricating titanium alloy bars with high efficiency, low cost, and high quality by means of b/(a + b) working, and the puzzles and challenges in the future are also pointed out.
