【Abstract】 The isothermal forging process has been widely used in the manufacturing of titanium alloy components for aerospace applications due to its advantages in near-net forming of complex shaped and high-performance titanium alloy components. However, the microstructure control and performance optimization of isothermal forged titanium alloys highly depend on the precise design of subsequent heat treatment processes. This article reviews the research progress and development trends of isothermal forging titanium alloy heat treatment processes, with a focus on analyzing the effects of heating temperature, holding time, cooling method, and typical processes on its microstructure evolution and mechanical properties. The solution-aging process can significantly improve the strength of titanium alloy isothermal forgings and is suitable for high load-bearing critical components. Air cooling process helps to control the microstructural gradient of complex components. Slow cooling followed by aging treatment can effectively improve toughness and meet fracture resistance requirements. Looking ahead to the future, the development of heat treatment process of isothermal forging titanium alloy requires the integration of numerical simulation and advanced energy field technology. It is recommended to focus on the comprehensive application of heat treatment numerical simulation, microwave-assisted treatment, cryogenic treatment, and low-temperature vacuum heat treatment.更多还原
