Abstract With the rapid development of aviation industry, the market share of large-scale, integral, precision and high-performance die forgings in aviation key components is expanding. The increasing size, complexity and material strength of aviation key components have brought great challenges to the overall die forging of large aviation key components. Firstly, the critical challenges and solutions of realizing the integral die forging of large aviation key components were introduced in this paper. Then, the research progress of integral precision die forging technology in typical large aviation key components such as aircraft bulkhead, landing gear and engine turbine disk was discussed. Finally, the future development of integral die forging technology of large aviation key components was prospected.
