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.
An extruded composition comprising a primary metal or metal alloy and having a length, the extruded composition comprising filaments extending axially along at least a portion of the length of the extruded composition, wherein the filaments comprise a secondary metal or metal alloy and a cross-section of the extruded composition perpendicular to the length comprises at least 25 filaments.
An extruded composition comprising a primary metal or metal alloy and having a length, the extruded composition comprising filaments extending axially along at least a portion of the length of the extruded composition, wherein the filaments comprise a secondary metal or metal alloy and a cross-section of the extruded composition perpendicular to the length comprises at least 25 filaments, wherein at least one filament in the cross-section of the extruded composition has an average cross-sectional surface area of between about 1 nm2 to about 10 cm2.
A copper extrusion product comprising filaments extending axially along at least a portion of the length of the copper extrusion product, wherein the filaments comprise aluminum, antimony, magnesium, tin, zinc, or any combination thereof, and a cross-section of the copper extrusion product perpendicular to the length comprises at least 25 filaments.
