摘要： A light metal composite material reinforced by alumina-silica fibers and a method for producing same. The composite material can have high mechanical qualities such as high workability and high wear resistance as well as high thermal qualities such as high fatigue resistance and high thermal conductivity and can also have high mating performance not to cause much wear of the mating member when the assemblage of alumina-silica fibers incorporated in the composite material as reinforcing members includes not more than 17 wt. % non-fibered particles, particularly not more than 7 wt. % of non-fibered particles of not smaller than 150 microns diameter, and has a virtual density of 0.08-0.3 g/cm.sup.3. The efficiency of production of the composite material is improved by binding the alumina-silica fibers provisionally with one another by an inorganic binder to have a compression strength no lower than 0.2 kg/cm.sup.2.

摘要： An engine piston is formed with a top crown surface and a top ring groove. An upper annular land surface is defined between the top ring groove and the edge of the top crown surface. The upper annular land surface and the side walls of the top ring groove are defined by a part of the piston which is formed of a matrix metal reinforced with inorganic fibers. The proportion of the inorganic fibers by volume in the reinforced part of the piston may optionally be approximately between 2% and 10%. A method for making such a piston includes forming a mass of inorganic fiber into an approximately cylindrical shape, placing it against the edge of the bottom surface of a hollow cylindrical lower mold, pouring molten metal into the lower mold to cover the inorganic fiber, sliding an upper mold into the lower mold and pressurizing the molten metal to infiltrate it between the inorganic fibers until complete solidification, removing the solidified mass of metal and entrapped inorganic fiber from the lower mold, and machining it to form a piston, with the fiber reinforced parts defining the upper ring groove side walls and the upper land surface.

摘要： A fiber reinforced metal type composite material. The reinforcing fiber is alumina fiber formed from at least 80% by weight alumina and the remainder silica, with the alpha alumina content of the alumina approximately between about 5% and about 60% by weight of the total amount of alumina. The matrix metal is selected from the group consisting of aluminum, magnesium, and their alloys. Thereby mechanical strength, resistance to wear, and workability of the fiber reinforced metal type composite material are good, and also friction wear on elements which frictionally rub against and mate with components made of the fiber reinforced metal type composite material is low.

摘要： A method for making a composite material. Porous reinforcing material such as fiber material is charged into a container which has an opening; then substantially all of the atmospheric air in the container and in the interstices of the reinforcing material is replaced by substantially pure oxygen; and then molten matrix metal is admitted into the container through the opening so as to infiltrate into the interstices of the reinforcing material. During this infiltration the oxygen within the container and in these interstices is absorbed by an oxidization reaction, and thus substantially all the gas present within the interstices of the reinforcing material is disposed of, thus not hampering the good infiltration of the molten matrix metal into the reinforcing material. Thus a high quality composite material is formed. The oxidization reaction may either be with the molten matrix metal itself, or with a getter element provided within the container.

摘要： An alloy is made of a first material and a second material which has a substantially lower melting point than the first material, by (a) forming from the first material a body which has multiple fine interstices; (b) pouring the second material in the molten state around the body formed from the first material; and (c) allowing the resultant mass to cool. Thus, in the parts of the resultant mass in which the body formed from the first material was originally present, an alloy mass comprising the first metal and the second material alloyed together is made. Optionally, the body made from the first material may be preheated, desirably to a temperature higher than the melting point of the second material; and optionally the molten second material may be pressurized so as to enter into the interstices of the body. The first material may desirably be, for example, tungsten, cobalt, chromium, titanium, iron, nickel, silicon, manganese, copper, niobium, tantalum, vanadium, gold, silver, aluminum, molybdenum, zirconium, or zinc; and the second material may desirably be, for example, aluminum, magnesium, copper, lead, tin, or zinc.

摘要： First a quantity of reinforcing material is formed into a shaped mass bound together by an inorganic binder. Next, this shaped mass is compounded with a quantity of a molten matrix metal by a pressure casting method. The molten matrix metal includes a quantity of a certain element with a strong tendency to become oxidized, and the inorganic binder includes a metallic oxide which, when brought into contact at high temperature with this certain element, is reduced thereby in an exothermic reaction. Thus, during the pressure casting, extra heat is produced as the certain element reduces the metallic oxide, and this aids good penetration of the matrix metal into the interstices of the reinforcing material. The metal remaining from the oxide is dispersed in the matrix metal. This metallic oxide may be silica, zirconia, chromium oxide, yttrium oxide, cerium oxide, ferric oxide, zirconium silicate, antimony oxide, or a mixture thereof; and the certain element may be lithium, calcium, magnesium, aluminum, beryllium, titanium, zirconium, or a mixture thereof.
