| Abstract Scope |
Pulsating hydroforming and impact hydroforming are two advanced technologies to increase the formability of material compared with other traditional forming technologies. They were systematically investigated from aspects of technical principle, forming mechanism, equipment and applications. Pulsating hydroforming can improve the forming ability by altering the friction condition of sheet/tube parts or by utilizing the effect of transformation induced plasticity of stainless steels under the pulsated loading. As for impact hydroforming, the strain rate can reach 103~104/s and the instantaneous pressure can be GPa level, which can obviously increase the elongation of hard-to-form material by 20%~60%. The effect of flexible liquid and impact impulse was investigated by both experiment and simulation, while the mechanisms are related to the compatible deformation of second phase, strain decentralization and defect stabilization. The technologies have been used on the manufacturing of complex, thin walled components for the fields of aeronautics and aerospace, automobile, nuclear power. |
