摘要： Molten metal of a first composition flows out of a first chamber via an open first control apparatus into a mold cavity. The first control apparatus is closed. A second control apparatus is opened. Molten metal of a second composition, different from the first composition, flows out of a second feed chamber via the second control apparatus into the mold cavity. At least a portion of the first composition metal in the mold cavity is sufficiently molten that an initial feed of the second composition molten metal mixes with the first composition molten metal in the mold cavity. An ingot is removed from the mold cavity, the ingot having top, middle, and bottom sections, the bottom section composed of metal of the first composition, the top section composed of metal of the second composition, and the middle section composed of a mixture of metal of the first and second compositions.

摘要： A method of fabricating MMCs having high thermal conductivity coupled with coefficient of thermal expansion (CTE) values which approximates the CTE of ceramics and semi-conductor materials typically used in electronic packaging. The method comprises preparing a formed agglomeration of powder particles (preform); partially sintering the preform; placing the partially sintered preform into a forming chamber; infiltrating the preform with liquid-phase metal; and allowing the liquid-phase metal to solidify and form an MMC around and through the preform. In a preferred embodiment, the preform is constructed from silicon carbide, and the metal matrix is an aluminum-silicon alloy.
