Fully hydroformed RF cavities [PDF]
Proceedings of the 1989 IEEE Particle Accelerator Conference, . 'Accelerator Science and Technology, 2003 Niobium-coated copper cavities are an attractive solution for RF superconducting structures. The copper parts are usually obtained by spinning and subsequent weldings. However, the defects of welded surfaces may create local coating problems. One way to minimize them is to hydroform monolithic cavities starting from OFHC (oxygen-free high-conductivity)

Springback Estimation in the Hydroforming Process of UNS A92024-T3 Aluminum Alloy by FEM Simulations
Metals, 2018 The production of metal parts manufactured through the hydroforming process is strongly affected by the difficulty in predicting the elastic recovery (springback) of the material. In addition, the formation of wrinkles and crack growth should be avoided.
