  • Publication number: 20140127069
    Abstract: Disclosed is a method of manufacturing a metal matrix composite in which oxide nanoparticles are dispersed. Metal matrix composite powders in which oxide nanoparticles are dispersed are prepared. Gibbs free energy of the oxide nanoparticles is greater than that of an oxide of a metal matrix. A bulk processed material is manufactured from the composite powders through hot forming or a cast material is manufactured by inputting the composite powder into a molten base metal and then rapidly stirring a resultant mixture. The bulk processed material or the cast material is heat-treated so that atoms of the metal matrix and atoms of the oxide nanoparticles mutually diffuse. Oxygen atoms originating from the oxide nanoparticles are diffused and dispersed in the metal matrix.

  • Publication number: 20140087202
    Abstract: The invention relates to a metal matrix ceramic composite and manufacturing method and application thereof. The metal matrix ceramic composite, is completely formed by permeating at least part of a matrix metal into an array of ceramic granules by means of squeeze-casting, and the volume percentage of the ceramic granules may be adjusted within a range of 10%-80% of the metal matrix ceramic composite according to the usage requirements. The metal matrix ceramic composites can not only retain high performance of anti-penetration, but also have the strong toughness of the metal; in addition, this composite has features of low density, resistance against ordinary mechanical cutting and flame cutting, and inhibition of crack propagation and the like. Therefore, said composite has broad application prospects in the protection of such important security facilities as safes, automatic teller machines and vault gates.

  • Patent number: 8608867
    Abstract: A method for the individualization of a metallic material by means of a carbon-containing basic material of organic origin is proposed. The novel method makes it possible to produce individualized ornamental alloys and individualized symbolic articles, such as pieces of jewelry, in a first step a carbon-containing organic basic material, which originates from at least one specific clearly identifiable person or a clearly identifiable group of persons, being converted into a carbonized initial material, and, in a second step, a physical and chemical incorporation of at least a fraction of the carbonized initial material into the metallic material taking place. The novel method and the novel ornamental alloys make it possible to produce symbolic articles with a direct material or substantive relation to a desired person by simple means, without creative freedom being restricted.

  • Patent number: 8561725
    Abstract: A drill collar formed substantially entirely from a metal matrix material and one or more metal alloys, the drill collar being produced through a molding process. The metal matrix material of the drill collar minimizes lateral movement and vibration during drilling operations, while providing a weight greater than that of conventional drill collar materials, thereby enabling construction of drill collars and bottom hole assemblies having a reduced length.

  • Publication number: 20130269902
    Abstract: Some embodiments provide methods and systems for casting articles. One example of a method includes providing and positioning a thermal blanket within a mold cavity and then introducing a molten material into the mold cavity and into contact with the thermal blanket. The method allows the molten material to remain in a molten state during a dwell time that extends from the introduction of the molten material at least until the mold cavity is filled. In another example, a method of using a thermal blanket includes keeping a molten material in a molten state during a dwell time extending from first introduction of the molten material until pressurization. Systems including a variety of mold types, one or more thermal blankets, and in some cases preforms and/or inserts are also provided. Also described is a novel thermal blanket and method of manufacturing the same.
