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.

A stirring device to be used for stirring a semi-solid metal slurry, wherein the stirring device is to rotate around a rotational axis (X-X) when used for stirring a semisolid metal slurry. The stirring device includes an elongated shaft extending along the rotational axis (X-X), and at least two wings securely arranged to the elongated shaft and extending radially outwards from the elongated shaft, wherein the at least two wings also have a substantial axial extension along the rotational axis (X-X). Hereby, whirls are produced in the slurry that results in a well-homogenized slurry with no large metal oxide surfaces inside. Disclosed is also a production method and a system for producing the slurry.

A method and apparatus for producing solid alloy components from its liquid state are provided. The molten alloy is rapidly cooled using a chill to temperatures below the thermosolutal transition temperature of the alloy. Finite-amplitude acoustic vibration is applied on the chill to shake off dendrites that form on the chill surface, to stir the slurry containing the fragments of dendrites, and to shake off slurry material that sticks on the surface of the chill as the chill is separating from the slurry. The slurry is then immediately poured into a chamber of a forming machine or a mold cavity shaped into solid components.

The present invention provides a high thermal conductivity aluminum alloy, which comprises the following components in percentage by weight: Al: 80%-90%; Si: 6.5%-8.5%; Fe: 0.2%-0.5%; Zn: 0.8%-3%; V: 0.03%-0.05%; Sr: 0.01%-1%; graphene: 0.02%-0.08%. In the high thermal conductivity aluminum alloy of the present invention, alloying elements including Si, Fe, and Zn are optimized; Sr, V, graphene, among others are added. The amount of each component is controlled so that they coordinate to ALLOW high thermal conductivity, good casting performance and excellent semi-solid die-casting property. Graphene is introduced to the high thermal conductivity aluminum alloy of the present invention to exploit the good thermal conductivity of graphene, allowing the formation of a high thermal conductivity aluminium alloy.

A method for manufacturing an electrical conductor includes: depositing a solid metal conductive layer or film on a substrate 30; depositing a liquid metal on the solid layer; and allowing the liquid metal and the solid layer 40 to alloy by diffusion of the liquid metal into the solid layer or film so as to form a solid conductive layer or film of the alloy; as well as allowing the liquid metal to further infiltrate the alloy so as to form percolating paths and/or droplets of the liquid metal in the the solid conductive layer or film, thus forming a biphasic conductive layer.

A process for preparing molten metals for casting at a low to zero superheat temperature involves the steps of placing a heat extracting probe into the melt and at the same time vigorous convection is applied to assure nearly uniform cooling of the melt. Then, the heat extraction probe is rapidly removed when a low or zero superheat temperature is reached. Finally, the rapidly cooled melt is quickly transferred to a mold for casting into parts or a shot sleeve for injection into a die cavity. The process may be carried out so as that small amounts of solid form in part of the melt. In this case, a key aspect of the invention is to carry out the process rapidly in order to maintain the particles in a fine, dispersed state that will not impede flow and will improve the quality of the metal parts produced. Cost of the metal parts produced is lowered due to longer die life and shorter cycle time.
