摘要： Embodiments of the present invention provide composite bodies having a discontinuous graphite preform and at least one silicon-bearing metal alloy infiltrant. Embodiments of the present invention also provide methods for producing such composite bodies. The metal alloy is preferably comprised of aluminum, copper, or magnesium, or combinations thereof. Certain preferred embodiments provide at least one aluminum alloy having from about 5% silicon to about 30% silicon, more preferably from about 11% to about 13% silicon, as an alloying element. Certain presently preferred embodiments provide an aluminum-silicon eutectic composition having about 12.5% silicon. Embodiments of the invention provide composite materials be “tuned” to more closely match thermal expansion characteristics of a number of semiconductor or integrated circuit materials such as, but not limited to, silicon, alumina, aluminum nitride, gallium nitride, and gallium arsenide while also providing high thermal conductivity. Embodiments of the present invention are especially suited for use as a heat sink, a heat spreader, or both.

摘要： Disclosed are economical methods and apparatus for high throughput pressure infiltration casting. Methods of the invention use a mold vessel as an evacuation chamber along with an evacuation cap to produce superior quality near-net shape finished cast parts with low porosity. Other methods of the invention use an improved heat transfer technique for directionally solidifying molten infiltrant at an increased rate to increase further the throughput of the pressure infiltration casting cycle. The invention also provides apparatus for practicing methods for high throughput pressure infiltration casting. One embodiment of an apparatus of the invention is a removable evacuation cap, often used in conjunction with a fill tube. Another apparatus embodiment is an evacuation cap coupled to a mold vessel which is used as an evacuation chamber.

摘要： A mold cavity in a mold vessel is evacuated. A charge of molten infiltrant is transported into the mold vessel while the vacuum is maintained in the mold cavity. Pressure is applied to the molten infiltrant to move the molten infiltrant from the mold vessel into the mold cavity. The molten infiltrant is cooled in the mold cavity to solidify the infiltrant. A fill tube can be used to transport the infiltrant to the mold vessel.
