Abstract: For forming a preform of composite material, such as aluminum-based composite material (MMC) by using friction during the forming thereof, ceramic reinforcement, such as Al2O3 and binder are prepared, and the prepared reinforcement and the silanor group binder are put into a die for press forming. During the forming, polycondensation occurs due to frictional heat generated between the fibrous or grain-like particles of the reinforcement and the silanor group binder to harden it, thereby obtaining a preform in which the particles of the reinforcement are fixedly connected to one another.

Abstract: A method is provided for producing a preform structure which is used in a composite aluminium or aluminium alloy component in which a base metal of an aluminium or aluminium alloy is reinforced with reinforcing materials. A slurry is prepared by mixing reinforcing materials including ceramic particles and first whiskers with burning-away powders and liquid. Liquid components contained in the slurry are filtered to provide a dehydrated structure. Thereafter a preform structure is produced by sintering the ceramic particles with the first whiskers after burning the burning-away powders in the dehydrated structure.

Abstract: The present invention relates to the use of a gating means in combination with a spontaneous infiltration process to produce a metal matrix composite body. Particularly, a permeable mass of filler material or a preform is spontaneously infiltrated by molten matrix metal to form a metal matrix composite body. A gating means is provided which controls or limits the areal contact between molten matrix metal and the filler material or preform. The use of a gating means provides for control of the amount of matrix metal which can contact the preform or filler material, which may result in less machining of a formed metal matrix composite body compared with a similar metal matrix composite body made without a gating mean. Moreover, the use of a gating means ameliorates the tendency of a formed metal matrix composite body to warp due to the contact between the formed composite body and matrix metal carcass.

Abstract: A hard drive disk substrate is formed of a multi-phase ceramic-based material having at least two phases with amorphous phases being present in an amount less than about 1 volume percent based on the volume of the ceramic-based material or at least one phase being free metal. A process for producing the ceramic-based disk substrate is produced by forming a flat disk of a porous ceramic and then infiltrating the porous ceramic with a metal whereby a multi-phase ceramic-based computer hard drive disk is produced. Additionally, a step of passivating the porous ceramic by elevating it to a temperature of about 1300.degree. to about 1800.degree. C. before the infiltrating step may be performed, such that the surfaces are passivated and the reaction kinetics can be controlled during the infiltrating step. A preferred composite material is made of a multi-phase boron carbide composite material including grains having peaks with an average roughness value, Ra, of between about 1 to about 200 .ANG., the roughness value being formed in situ by causing a micro hardness gradient of between about 19 and about 3200 Kg/mm.sup.2 in the various phases of the multi-phase boron carbide composite material.

Abstract: A method for producing an aluminum alloy composite material comprises disposing in a mold, in sequence from bottom to top, an infiltration enhancer containing Mg, a preform and an aluminum matrix alloy ingot, and then inserting the mold into an atmospheric furnace. The interior of the atmospheric furnace is then turned into an argon atmosphere. Thereafter, the internal temperature of the furnace is raised to a first predetermined temperature which is maintained for a given period of time so that the infiltration enhancer sublimates to permit the Mg component thereof to infiltrate into the preform. The atmosphere inside the furnace is then turned from the argon atmosphere into a nitrogen atmosphere. Thereafter, the internal temperature of the furnace is raised to a second predetermined temperature higher than the first predetermined temperature and maintained for a given period of time so that the aluminum matrix alloy ingot melts to permit the aluminum matrix alloy to spontaneously infiltrate into the preform. The interior of the furnace is then cooled to thereby produce an aluminum alloy composite material of high-quality.
