    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.

    摘要: A composite material is manufactured from a formed mass of reinforcing material and matrix metal by introducing the reinforcing material mass into a pressure chamber and holding it there, introducing molten matrix metal into the pressure chamber so as to surround the reinforcing material mass, moving the reinforcing material mass from the pressure chamber into a casting chamber of substantially smaller volume than the pressure chamber while it is still being surrounded by molten matrix metal, and then allowing the molten matrix metal to solidify while applying pressure. If the reinforcing material mass is preheated before being put into the pressure chamber, it can be kept away from the walls of the pressure chamber until after the molten matrix metal has been poured into the pressure chamber and thus will not lose heat to them; and, since the casting chamber can quite tightly conform to the size and shape of the reinforcing material mass, little extra matrix metal needs to be solidified around the reinforcing material mass. Accordingly the resulting composite material can be easily isolated without the need for much post machining.

    摘要: A method of producing a composite material from porous reinforcing material and molten matrix metal. First the porous reinforcing material is heated up to a temperature substantially above melting point of the matrix metal. Then the molten matrix metal is infiltrated into the porous structure of the reinforcing material under a substantial pressure. Then the combination of the reinforcing material and the matrix metal infiltrated thereinto is cooled down to a temperature below the melting point of the matrix metal, while maintaining the abovementioned substantial pressure. Optionally, the reinforcing material may be charged into a case; and, again optionally, the case may have one opening only, and a vacant space may be left between another part of the case and the reinforcing material charged in the case, with the reinforcing material interrupting communication between the opening and the vacant space. The case can be made of stainless steel, or of a refractory material such as porous brick. Possible materials for the reinforcing material include fibers of alumina, carbon, boron, or stainless steel; and possible materials for the matrix metal include aluminum and magnesium.
