Heterogeneous and complex structures have the advantages of lightweight, integration of structural functions and extreme performance functions, and are increasingly widely used in aviation manufacturing, integrated circuits, ocean engineering, microwave radar, instrumentation and other fields, and are important supports for innovative design and advanced manufacturing of high-end equipment. The combination interface of heterogeneous and complex structures is abrupt, time-varying, changeable and changeable, which requires higher and higher feasibility and reliability of the connection. How to realize the reliable connection of heterogeneous and complex structures, further break through the manufacturing limitations, and give full play to the ultimate performance has become a key technology for the innovation and development of high-end equipment. It is difficult to connect heterogeneous and complex structures, involving multiple disciplines such as machinery, materials, metallurgy, mechanics, thermodynamics, testing and standardization. As the structure of key components of high-end equipment becomes more complex and the service environment becomes extreme, The breakthrough of corresponding key technologies often requires the combination and integration of welding material metallurgy, ion beam surface activation, joint structure design, multi-energy field coupling and other technologies, and the research of these technologies has gradually become the research hotspot of the industry. This album aims to showcase important advances in relevant research fields at home and abroad, and is expected to arouse the interest and attention of readers and researchers, and further stimulate the enthusiasm and vitality of scientific research on the connection of heterogeneous and complex structures.
