Abstract (en)
[origin: CA2008371A1] Method and Device for Producing Dispersion-hardened Shaped Metal Parts Method and device for producing dispersion-hardened shaped metal, e.g. copper parts, wherein a copper melt is produced that is superheated by a maximum 300.degree.C, which melt is supersaturated with boron and one or several boride-forming elements of the groups IVA, VA and VIA in the periodic system and/or aluminium in such a way that a homogeneous, largely stable boride dispersion forms abruptly in the supersaturated melt, and wherein a given quantity of this boride-containing copper melt is either directly prepared in the female die or metered into it and, immediately after having been prepared or metered in, shaped by means of a male die, preferably applying compacting pressure, and caused to solidify before the finished or near-net-shape copper part is removed. The method is efficient and flexible, and it is possible to produce high-quality parts in simple devices that are easy to automate, making optimum use of the material.
