    Abstract: The invention offers a magnesium alloy sheet material having excellent plastic processibility and rigidity and a magnesium alloy formed body having excellent rigidity. The sheet material has magnesium alloy that forms the matrix containing hard particles. The region from the surface of the sheet material to a position away from the surface by 40% of the thickness of the sheet material is defined as the surface region, and the remaining region as the center region. Hard particles existing in the center region have a maximum diameter of more than 20 μm and less than 50 μm, and hard particles existing in the surface region have a maximum diameter of 20 μm or less. Because the hard particles existing at the surface side are fine particles, they are less likely to become the starting point of cracking or another defect at the time of plastic processing. Because the hard particles existing in the center region are coarse, they can increase the rigidity of the sheet material.

    Abstract: Metal-matrix composites with combinations of physical and mechanical properties desirable for specific applications can be obtained by varying and controlling selected parameters in the material formation processes, particularly by increasing the microstructural homogeneity of the composite, while maintaining a constant mixture ratio or volume fraction. In one embodiment of the invention, a CuSiC composite having increased thermal conductivity is obtained by closely controlling the size of the SiC particles. In another embodiment of the invention, AlSiC composites which exhibit increased ultimate tensile and yield strengths are made by closely controlling the size of SiC and Al particles.

    Abstract: Although MIM (metal injection molding) has received widespread application, aluminum has not been widely used for MIM in the prior art because of the tough oxide layer that grows on aluminum particles, thus preventing metal—metal bonding between the particles. The present invention solves this problem by adding a small amount of material that forms a eutectic mixture with aluminum oxide, and therefore aids sintering, to reduce the oxide, thereby allowing intimate contact between aluminum surfaces. The process includes the ability to mold and then sinter the feedstock into the form of compacted items of intricate shapes, small sizes (if needed), and densities of about 95% of bulk.
