DUAL-PHASE HOT EXTRUSION OF METALS

摘要

The present disclosure provides a method of dual-phase hot metal extrusion comprising (i) providing a load carrier made of a first metal material, wherein the load carrier comprises one or more load chambers containing a second metal material, wherein the melting point of the second metal material is lower than the melting point of the first metal material, (ii) heating the load carrier to a temperature above the melting point of the second metal material and suitable for extrusion of the load carrier, and (iii) extruding the load carrier to form an extruded product. The present disclosure also provides apparatuses for accomplishing the dual-phase hot extrusion of metals and products resulting from such processes.

主权项

1. A load carrier, suitable for dual-phase hot metal extrusion and made of a first metal material, comprising a load end, a blind end, and at least one load chamber having a depth extending axially from the load end towards the blind end, wherein the at least one load chamber comprises a load material and a void space, wherein the load material comprises a second metal material, the second metal material having a lower melting point than the melting point of the first metal material, and wherein the void space is configured to accommodate at least a portion of the second metal material in its molten form when the load carrier is heated.
