    Abstract: The present invention relates to a process for the production of components for combustion engines or turbines, in particular for the production of hollow-valve components, with which for the first time powdery titanium-based alloys, in addition to conventional materials, can be processed into these components. In the process, metal powder and/or metal alloy powder are mixed in a compounder with a binding agent and optionally a flux, the mixture is shaped by injection moulding, the shaped compound is chemically debound, the chemically debound compound is thermally debound at a temperature of less than 450° C. and the chemically and thermally debound compound sintered at a temperature below the melting temperature of the metal and/or metal alloy for the production of the component. The components can be combined with each other in conventional manner by form- and force-locking and also molten joining processes.
