Abstract
The method of warm hydroforming, special with oil, is researched in detail, for example by the Fraunhofer Institut Chemnitz. The reason of this research is the improvement of formability of leightweight alloys. Especially magnesium shows a great rise of formability at elevated temperaturs. For that, the matrice of oil limits the use of this method in relation to the temperature. Gaseous mediums, special nitrogen, is able to break this barrier. In this diploma safety instructions in relation to operators and the system are mentioned by calculating the sound level respective the behaviour of nitrogen by elevated temperatures at first. The feasibility of this method is proven by the produced parts.
