PROCEDURE FOR PRODUCTION IN A FORM NEXT TO THE FINAL CONTOUR OF COMPONENT PARTS OR SEMI-FINISHED PRODUCTS BASED ON ALLOYS OF LIGHT METALS DIFFICULTLY MACHINABLE WITH STARTING OF CHIPS.

摘要

Procedure for the production in a form close to the final contour of component parts or semi-finished products based on lightly machinable light metal alloys with chip removal, covering the following stages: S making available a powder material, consisting of a light metal and possibly additives of hard material particles, as a wear resistance bearing element, and / or other alloy metal additives; then S isostatically press the powder material to give a molded body; and S subjecting the molded body to an extrusion process at a temperature close to that of sintering the light metal without sintering of the pressed molded body before extrusion.
