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.
