Special Issue Information

Dear Colleagues,

The local loading forming process represents an advanced, efficient, and high-quality metal forming technology, which is particularly suitable for forming high-performance components with complex geometric structures and extreme performance requirements. Compared with traditional overall loading forming processes, the local loading forming process realizes the overall plastic forming of components by applying loads successively and in different zones. This not only significantly reduces the forming load but also enables precise control over metal flow and plastic deformation, and remarkably improves the microstructure of the components. As a result, it breaks through the forming limits of complex components and enhances their mechanical properties. Therefore, the local loading forming process signifies an important approach to achieving the high-performance manufacturing of key components for high-end equipment, and it has already become a research hotspot in the forming and manufacturing technology of high-performance components.

Research on local loading forming involves several key aspects, including the local deformation mechanism, metal flow behavior, stress–strain distribution, die design, and process optimization. To improve the adaptability and efficiency of the process, researchers have explored various new methods such as multi-degree-of-freedom envelope forming, incremental forming, and combined extrusion–spinning forming technology. These advancements contribute to the development of the theoretical understanding and technology of local loading forming, endowing it with broader application prospects in fields such as aerospace, weaponry, energy, and automotives.

In order to further promote the development of this field, this Special Issue invites researchers to discuss new methods of local loading forming, process modeling, experimental studies, and industrial applications. By addressing the challenges and opportunities in this field, we hope to stimulate technological innovation and accelerate the application and dissemination of local loading forming technology in the field of high-end equipment manufacturing.

Aiming at the technical challenges in the Multi-DoF forming of 20CrMnTi high-ribbed ring-groove components, including complex metal flow behavior that easily causes under-filling defects and complicated die stress states prone to die failure, this paper proposes an optimal design method for the Multi-DoF forming process of high-ribbed ring-groove components. The influence mechanism of different blank sizes on metal flow and component filling effect is systematically investigated, and three typical metal flow modes are identified. Furthermore, a die stress optimization method for Multi-DoF forming is proposed. Research results show that, compared with the outward-to-inward and inward-to-outward metal flow modes, the metal flow under the symmetric inward–outward flow metal flow mode is more balanced, ensuring that the two high ribs can be fully formed. Additionally, changing the blank size can balance the forces on both sides of the die boss, thus significantly reducing the risk of die cracking caused by stress concentration. On the basis of the above research results, experimental tests are conducted, and the high-ribbed ring-groove components achieve full forming quality without die failure, which verifies the feasibility and effectiveness of the process optimization design method proposed in this paper.
