The application of aluminum alloys is becoming increasingly prevalent in the automotive and aerospace industries, where the collaborative control of shape and performance is critical for ensuring the high quality of alloy components. A thorough understanding of the evolution and regulation mechanisms governing the characteristic microstructures of materials and components under thermal and mechanical fields is essential for advancing high-performance forming manufacturing. This study focuses on the collaborative shape-performance manufacturing of aluminum alloy thin-walled components through plastic forming. By analyzing the characteristic microstructures that underlie the superior comprehensive performance of these components, the report explores the principles and processes involved in high-performance precision forming. Emphasis is placed on two combined regulation strategies: dislocation-precipitate interactions and dissolution-reprecipitation processes. The precise control of characteristic microstructures achieved through these mechanisms offers a promising pathway to address the critical challenges in high-performance manufacturing of aluminum alloy thin-walled components.
