Abstract: There are disclosed a method for producing a composite material composed of a dispersing agent and a matrix, and a composite material produced by the method. The matrix is formed by the steps of coating a metal-coated dispersing agent to form a metal-coated layer on the surface of the dispersing agent, filling the metal-coated dispersing agent in a jig prepared in a fixed shape, and then causing the reaction of the metal-coated layer with a molten Al by impregnating the metal-coated dispersing agent with the molten Al filled in the jig.

Abstract: The present invention is directed to a method for making porous aluminum product and products therefrom and, in particular, a method of rapidly solidifying a liquid metal foam produced by the incorporation of gas forming agents into an aluminum melt. The aluminum melt may be stabilized to support the creation of liquid metal foam by the addition of metal and/or ceramic additives. The decomposition of the gas forming agents and subsequent expansion of the gaseous products is controlled through the use of a reactor, wherein temperature, pressure and transit time can be adjusted to match the decomposition kinetics of the gas forming agent. The invention allows for the economical production of liquid metal foam of uniform cell size that can be continuously cast into sheet, plate and profile sections. Such metal foam products may be used in structural, thermal and acoustic applications.

Abstract: Diamond heat spreaders are produced having thermal properties approaching that of pure diamond. Diamond particles of relatively large grain size are tightly packed to maximize diamond-to-diamond contact. Subsequently, smaller diamond particles may be introduced into the interstitial voids to further increase the diamond content per volume. An interstitial material is then introduced which substantially fills the remaining voids and should have favorable thermal properties as well as form chemical bonds with the diamond. Alternatively, the packed diamond may be subjected to ultrahigh pressures over 4 GPa in the presence of a sintering aid. The resulting diamond heat spreader has diamond particles which are substantially sintered together to form a continuous diamond network and small amounts of a sintering agent. The final heat spreader exhibits superior heat transfer properties advantageous in removing heat from various sources such as electronic devices and minimized difference in thermal expansion from the heat source.

Abstract: A product in which at least a portion of the product has a nanocrystalline microstructure, and a method of forming the product. The method generally entails machining a body in a manner that produces chips consisting entirely of nano-crystals as a result of the machining operation imposing a sufficiently large strain deformation. The body can be formed of a variety of materials, including metal, metal alloy and ceramic materials. Furthermore, the body may have a microstructure that is essentially free of nano-crystals, and may even have a single-crystal microstructure. The chips produced by the machining operation may be in the form of particulates, ribbons, wires, filaments and/or platelets. The chips are then used to form the product. According to one aspect of the invention, the chips are consolidated to form the product, such that the product is a monolithic material that may contain nano-crystals. According to another aspect of the invention, the chips are dispersed in a matrix material, such that the product is a composite material in which the chips serve as a reinforcement material.

Abstract: A brake drum includes a ring-shaped drum body (13), and a friction member (16) secured to the inner circumferential surface (18) of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum can be reduced in weight as a whole. Further, because the friction member, having projecting portions (17a) formed on its outer periphery (17), is cast-enveloped by molten metal of the Al alloy, the friction member and the drum body can be firmly fastened together. Thus, even when a great braking force is applied to the drum brake, the friction member can be prevented from being undesirably detached from the drum body.
