A method (S) for manufacturing a part (1) out of a metal matrix composite material, including the following steps: opening (S1) a device (10) that includes a supporting portion (14) and a molding portion (14); placing (S2) a fibrous reinforcement into the device (10); sealably closing (S3) the device (10) by providing a space between the fibrous reinforcement (2) and the device portions; feeding (S4) the molten metal matrix (3) into the device (10) such as to fill the space between the fibrous reinforcement (2) and the device portions (13, 14); and applying (S5) a force onto the equipment (10) such as to impregnate the fibrous reinforcement (2) with the metal matrix (3).

A method of manufacturing an aluminum alloy cylinder head includes providing a precision sand core and mold assembly, a liquid aluminum alloy delivery system, and a mold manipulator system. The precision sand core and mold assembly is disposed in the mold manipulator system and the liquid aluminum alloy delivery system includes an in-furnace ultrasonic actuator and a launder tube having at least an ultrasonic actuator. The liquid aluminum alloy delivery system is sealed to the precision sand core and mold assembly and provides liquid aluminum alloy into a gating system of the precision sand core and mold assembly. The precision sand core and mold assembly is rotated approximately 180. The precision sand core and mold assembly is vibrated.

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.

Provided are an anti-fatigue in-situ aluminum-based nanocomposite material for heavy-load automobile hubs and a preparation method therefor. By means of the fine adjustment of components and a forming process, in situ nano-compositing, micro-alloying and rapid compression moulding techniques are combined. That is, after the addition of Zr and B, an in-situ reaction occurs to form a nano ZrB.sub.2 ceramic reinforcement, which is distributed in aluminum crystals and crystal boundaries and bonded to a metallurgical interface kept firm with the matrix.
