Hydroforming of hollow tubes is a manufacturing process for producing lightweight parts with a high strength/density ratio. For producing parts with a high forming degree multistage processes are used. This paper describes the development of a multistage hydroforming process for hollow tubes of titanium. After the investigation of important material properties a suitable heat treatment is investigated. Experimental results show the feasibility of hydroforming of titanium hollow tubes.

Publications about the project

Hydoroforming of titanium tubes was investigated by the Institut für Integrierte Produktion Hannover (IPH) and the Institute of Metal Forming Siegen. The basic research for designing a multi-stage process chain of hollow profiles made of titanium grade 2 was divided into three sub-items, the material model, the annealing treatment and friction value determination. The results were brought together in a simulation model, which enabled developing a multistage process chain.

In a research project by the Institut für Integrierte Produktion Hannover (IPH) and the Institute of Metal Forming Siegen the basics for hydroforming titanium tubes were investigated. The aim of this research project was to develop a multi-stage process chain for hydroformed parts made of titanium. First the method-specific material properties as well as the tribological system were examined. The results were combined in a simulation model which enabled the process development. Finally, the developed process chain was successfully tested using a real component and the trials were compared with the simulation results.
