Then, the developments of isothermal forging technology, precision rolling technology, integral forming technology for large complex component and forging process simulation were introduced, and the future research directions of forging technology for aviation titanium alloys were also discussed. In the isothermal forging processing, structural component heat treatment, die design and manufacture and heating and lubrication protection technologies need to be investigated intensively. In the precision rolling mill processing, thin-wall ring precision ring rolling technology, automatic control technology, ring expansion fixture and die design technology and operating device software development technology need to be further studied. In the large-scale complex structural component integral forming technology, incremental load precision die forging technology, multi-direction precision die forging technology, control technology of microstructure and property for the large-scale forging piece and precision forming technology of complex structural component need to be further researched. Simultaneously, the research, promotion and application of forging processing and equipment digitalization need to be carried out, and the forging processing design method based on numerical simulation should be established.
