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.

Solid aggregate material, at least 65 volume percent, is placed in a die, the die is evacuated and heated, and molten metal is driven by a piston to infiltrate the solid aggregate material where it subsequently solidifies to form a metal matrix composite.

摘要： Controlling the linear velocity of melt discharge from the discharge outlets of a melt distribution device so as to essentially negate reverse flow from the walls of the mold has been found to produce less oxides and less surface defects in an ingot, particularly an aluminum ingot. This discharge is controlled from the outset of the casting of an ingot because it has been found most defects occur within the initial phase of a cast. A melt distribution device, referred to as a "bag-in-a-bag", is provided which is a pressureless interiorly partitioned receptacle. The partitioning of the receptacle provides an outer bag and a melt-impermeable inner bag in which a pool of melt collects. The pool is deep enough to submerge the discharge end of a spout, to dissipate the kinetic energy of the incoming melt, and to distribute melt from a central zone to discharge zones on either side of the central zone. The discharge zones are provided with outlets through which the melt is discharged at a velocity in the range from about 40 in/min to about 100 in/min depending in part upon the drop rate and the size of the ingot to be cast. Desirable drop rates are in the range from about 2-10 in/min, preferably in the range from 3-7 in/min. A novel starting block is provided which confines the flow of melt so as to form a pool of melt in the center of the mold cavity before the rest of the ingot is cast.

摘要： A method of forming a ceramic-metal composite including steps of providing a body of ceramic material; infiltrating molten metal into open spaces of the body at an elevated pressure; cooling the metal to form a solid composite; and reacting a portion of the metal in the composite at an elevated temperature with an oxidizing gas. A particularly preferred composite is made by infiltrating an alumina body with an aluminum alloy and then oxidizing in air at an elevated temperature. The composite is useful for making armor plate and other products where a combination of high hardness, good strength, and light weight are needed.
