Abstract: The present invention relates to the formation of bodies having graded properties. Particularly, the invention provides a method for forming a metal matrix composite body having graded properties. The graded properties are achieved by, for example, locating differing amounts of filler material in different portions of a formed body and/or locating different compositions of filler material in different portions of a formed body and/or locating different sizes of filler materials in different portions of a formed body. In addition, the invention provides for the formation of macrocomposite bodies wherein, for example, an excess of matrix metal can be integrally bonded or attached to a graded metal matrix composite portion of a macrocomposite body. Moreover, if desired, it is possible to produce a metal matrix composite body with substantially the same properties throughout.

Abstract: The present invention relates to a novel process for forming thin metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltrating atmosphere are in communication with a filler material or preform, at least, at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Such spontaneous infiltration occurs without the application of any pressure or vacuum. In an embodiment of the present invention, the filler material may be sprayed upon a thin sheet of matrix metal. Alternatively, the filler material may be shaped via tape casting, slip casting, etc. to provide a thin preform. In another embodiment of the present invention, a body of matrix metal may be coated with a filler material such that upon spontaneous infiltration a metal matrix composite body is produced which inversely replicates the configuration of the original body of matrix metal.

Abstract: A method is described for preparing a refined or reinforced eutectic or hyper-eutectic metal alloy, comprising: melting the eutectic or hyper-eutectic metal alloy, adding particles of non-metallic refractory material to the molten metal matrix, mixing together the molten metal alloy and the particles of refractory material, and casting the resulting mixture under conditions causing precipitation of at least one intermetallic phase from the molten metal matrix during solidification thereof such that the intermetallics formed during solidification wet and engulf said refractory particles. The added particles may be very small and serve only to refine the precipitating intermetallics in the alloy or they may be larger and serve as reinforcing particles in a composite with the alloy. The products obtained are also novel.

Abstract: Metal-matrix composites and methods for producing these composites are provided. The manufacturing methods include providing a ceramic preform having a uniform distribution of ceramic particles sintered to one another. The particles include an average particle size of no greater than about 3 microns, and at least one half of the volume of the preform is occupied by porosity. The preform is then disposed into a mold and contacted by molten metal. The molten metal is then forced into the pores of the preform and permitted to solidify to form a solid metal-matrix composite. This composite is machinable with a high-speed steel (HSS) bit for greater than about 1 minute without excessive wear occurring to the bit. This invention preferably employs metal-matrixes including Al, Li, Be, Pb, He, Au, Sn, Mg, Ti, Cu, and Zn. Preferred ceramics include oxides, borides, nitrides, carbides, carbon, or a mixture thereof. Inert gas pressures of less than about 3,000 psi can be used to easily infiltrate the preforms.

Abstract: The present invention relates to a novel process for making a macrocomposite body. Specifically, a metal matrix composite body is first formed and thereafter, a ceramic body or a ceramic matrix composite body is caused to form from at least one surface of the already formed metal matrix composite body. The ceramic or ceramic composite body can be formed by, for example, changing from spontaneous infiltration conditions which permit a molten matrix metal to infiltrate a filler material or preform to conditions which favor the growth of a ceramic oxidation reaction product from the matrix metal (e.g., the matrix metal serves the dual role of a matrix metal and a parent metal for growth of oxidation reaction product). The growth of oxidation reaction product can occur from one or more surfaces of a metal matrix composite body and can be controlled to result in any desired shape. Moreover, the oxidation reaction product can be caused to grow directly into an atmosphere to form a ceramic body or can be caused to grow into an adjacently located filler material to form a ceramic matrix composite body. The oxidation reaction product can be formed substantially immediately after the metal matrix composite body is formed or may be formed at any point later in time.

Abstract: A net shaped ceramic-reinforced aluminum matrix composite is provided by forming a permeable mass of ceramic material with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy with the permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy can be placed adjacent to a permeable bedding of ceramic material having a barrier, and brought to the molten state, preferably to at least about 700.degree. C., in order to form the net shape aluminum matrix composite by spontaneous infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.

Abstract: A method for impregnating a metal product with a hard wear-resistant surface area comprises providing a wear-resistant layer in the form of a sintered sheet having a pattern which facilitates metallurgical bonding with a metal melt and optionally, at least one "pin" integrally attached onto a surface of the sheet. This wear-resistant layer is attached onto the sand core and a metal melt is cast so as to produce the final product. This method can be used to produce a variety of metal products although cast iron is preferred. Moreover, this process can effectively employ any of the hard phases which can be sintered, e.g., tungsten carbide, chromium carbide, and the like.

Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. Particularly, a permeable mass of filler material is formed into a preform. An infiltration enhancer or an infiltration enhancer precursor or an infiltrating atmosphere are also in communication with the preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the preform when the preform is placed into the molten matrix metal. A means for maintaining the preform at least partially below the surface of the molten matrix metal can also be utilized. In a preferred embodiment a reservoir may be employed to supply a second metal which has a different composition from the first source of matrix metal. By using a reservoir metal which is different in composition then the first source of matrix metal, it is possible to tailor the properties of the metal within the metal matrix composite body to meet various operating requirements and thus tailor the properties of the metal matrix composite body itself.
