Einrichtung zum Herstellen eines hohlen metallischen Elementes durch Diffusionsverbindung und superplastische Verformung, Verwendung derselben sowie Verfahren zum Herstellen eines solchen metallischen Elementes

摘要

The assembly has a tank (14) with an open end which is connected to a passage of a pile to allow communication between an internal space of the tank and a cavity. The tank is in-deformable to temperature and pressure of diffusion welding of the pile. The tank has a volume such that when the assembly is placed at a thermal degradation temperature of a binder, gases emitted from binder degradation are sucked into the tank. An Independent claim is also included for a manufacturing process of a hollow mechanical part.
