High strength-toughness titanium alloy has gradually attracted considerable attention as important engineering material in aerospace industry. Forging is a main thermomechanical processing method in high strength titanium alloy, With the major purposes of refining grain and optimizing mechanical properties through microstructure control during the different stages of thermomechanical process. The grain refinement occurs mainly in the process of ingot breakdown and substituting forging, which affects the static and dynamic recrystallization of the alloy by controlling the forging temperature and deformation. The microstructure control is mainly occurred in the finished forging stage by controlling the forging temperature and phase transformation of the alloy. This article describes the research development of the thermomechanical process for high strength-toughness titanium alloys, summaries the effect on the microstructure of thermalmechaical process from the two aspects of refining the grain and controlling the structure from.
