Process for the near-net-shape production of components or semi-finished products made of light-metal alloys that are difficult to machine, and component or semi-finished product produced by the method

摘要

The invention relates to a method for the near-net-shape production of components or semi-finished products made of hard-to-machine light metal alloys with the following steps: DOLLAR A - a powder material which has light metal and alloy components, in particular wear carriers, is provided; DOLLAR A - the powder material is pressed isostatically into a shaped body; and DOLLAR A - the molded body is subjected to an extrusion process near the sintering temperature of the light metal. DOLLAR A Furthermore, it relates to a component or semi-finished product produced by the method.
