摘要： A castable, moldable, or extrudable magnesium-based alloy that includes one or more insoluble additives. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure. The magnesium-based composite has improved thermal and mechanical properties by the modification of grain boundary properties through the addition of insoluble nanoparticles to the magnesium alloys. The magnesium-based composite can have a thermal conductivity that is greater than 180 W/m-K, and/or ductility exceeding 15-20% elongation to failure.

摘要： Disclosed is a preparation method of a magnesium matrix composite reinforced with SiC particles, belonging to the technical field of metallurgical materials, including the following steps: (1) carrying out oxidation pretreatment on SiC particles; (2) laying a piece of magnesium alloy on a bottom, laying a layer of oxidized SiC particles, then repeating a laying operation of a layer of magnesium alloy and a layer of SiC particles until the magnesium alloy and the SiC particles are completely laid, introducing inert gases, heating and melting, then performing cinder scrapping; (3) cooling to a semisolid temperature of the magnesium alloys for semisolid mechanical stirring, heating, and mechanically stirring again; (4) cooling again to the semisolid temperature of the magnesium alloys, then casting into a blank; and (5) heating the blank to the semisolid temperature of the magnesium alloys and extruding to obtain the magnesium matrix composite reinforced with SiC particles.

摘要： A high-thermal conductivity composite material is AlNp/ZA27 composite material, including 2%, 4%, 6%, or 8% by volume of aluminum nitride (AlN) ceramic particles and zinc-aluminium-27 (ZA27) alloy. The ZA27 alloy includes 70.52-71.08% by weight of Zn, 25.58˜27.65% by weight of Al, 1.27˜3.45% by weight of Cu, and 0.50% or less by weight of Mg. In the preparation of the high-thermal conductivity composite material, an as-cast AlNp/ZA27 composite material is subjected to homogenizing annealing and reciprocating extrusion.

摘要： A system of obtaining an aluminium melt including SiC particles for use when moulding vehicle parts, e.g. brake disks, the system comprises a pre-processing tank (2), configured to receive SiC particles and to apply a pre-processing procedure to pre-process the SiC particles; a SiC particle transport member (4) configured to transport the pre-processed SiC particles from the pre-processing tank (2) to a crucible (6) of a melting furnace device (8), and the melting furnace device (8) is configured to receive and melt solid aluminium, e.g. aluminium slabs, and to hold an aluminium melt (10) and to receive said pre-processed SiC particles (12). The system also comprises a tube-like SiC particle mixing arrangement (14) defining and enclosing an elongated mixing chamber (16), the mixing arrangement (14) is configured to be mounted in said crucible (6) and structured to receive into said mixing chamber (16) said pre-processed SiC particles (12) via a first inlet (18) and said aluminium melt (10) via at least one second inlet (20), and to apply a mixing procedure by rotating a rotatable mixing member (22) arranged in said mixing chamber (16) about said longitudinal axis A, wherein said pre-processed SiC particles are mixed together with the aluminium melt in said mixing chamber. The mixing arrangement (14) is provided with at least one outlet (26) to feed out the mixture from said mixing chamber into said crucible.
