Bestimmung des Umformverhaltens von Magnesium- und Aluminiumlegierungen beim temperierten Innenhochdruck-Umformen (T-IHU) mit flüssigen Wirkmedien

At the field of forming magnesium alloys are still remaining deficits in view of reachable forming results, optimal process parameters and process guidance. Because of that reasons experimental tests are carried out with concentration of the minimal edge radius. As an result of the diploma is a better calculation possibility for the minimal edge radius of hydroforming parts created and a formula with design of experiments detected. Determined factors are tool and fluid temperature, maximum pressure and thickness of the tubes. The results should enhance the knowledge about the specific material behaviour of magnesium and aluminium by elevated temperatures. In the end economic aspects of tempered hydroforming with concentration of necessary tools and equipments are given
