Publication number: 20120279412Abstract: In making frangible objects, including lead-free bullets and other projectiles, powdered metal primary and powdered ceramic secondary phases are mixed and densified at an elevated temperature such that the ceramic phase forms a brittle network. Different combinations of metal and ceramic phases may be used to achieve desired chemical and physical properties. Any appropriate mixing, forming, and/or thermal processing methods and equipment may be used. Degrees of frangibility, strength, and toughness can be adjusted to suit a given application by precursor selection, degree of mixing, relative amounts of metal and ceramic phases, forming method, and thermal and mechanical processing parameters.Type: ApplicationFiled: January 6, 2011Publication date: November 8, 2012Applicant: Ervin Industries, Inc.Inventors: Mark C.

Publication number: 20120276393Abstract: A multiphase composite system is made by binding hard particles, such as TiC particles, of various sizes with a mixture of titanium powder and aluminum, nickel, and titanium in a master alloy or as elemental materials to produce a composite system that has advantageous energy absorbing characteristics. The multiple phases of this composite system include an aggregate phase of hard particles bound with a matrix phase. The matrix phase has at least two phases with varying amounts of aluminum, nickel, and titanium. The matrix phase forms a bond with the hard particles and has varying degrees of hard and ductile phases. The composite system may be used alone or bonded to other materials such as bodies of titanium or ceramic in the manufacture of ballistic armor tiles.Type: ApplicationFiled: July 9, 2012Publication date: November 1, 2012Inventor: Robert G.

Patent number: 8282748Abstract: The invention relates to a method for producing metal matrix composite materials, including at least one proportion of magnesium or one magnesium alloy and involving at least one production step in which a thixomolding ensues. According to the invention, an Mg2Si phase having a volume fraction of at least 2% is incorporated in a metal matrix preferably comprised of magnesium or of a magnesium alloy. The inventive method uses the thixomolding method for the in-situ production of a metallic composite material and is advantageous in that a broad range of adjustable volume fractions of the Mg2Si phase in the composite material results whereby enabling the properties of the composite material to be individually modified. The inventive metal matrix composite material is particularly suited for producing thermally stressed parts of motor vehicles such as pistons or the like.Type: GrantFiled: October 16, 2004Date of Patent: October 9, 2012Assignee: Mahle GmbHInventors: Florian Moll, Lutz Oemisch, Ulrich Bischofberger, Karl Ulrich Kainer, Norbert Hort, Hajo Dieringa, Hagen Frank

Patent number: 8268452Abstract: Methods for forming earth-boring tools include providing a metal or metal alloy bonding agent at an interface between a first element and a second element and sintering the first element, the second element, and the boding agent to form a bond between the first element and the second element at the interface. The methods may be used, for example, to bond together portions of a body of an earth-boring tool (which may facilitate, for example, the formation of cutting element pockets) or to bond cutting elements to a body of an earth-boring tool (e.g., a bit body of a fixed-cutter earth-boring drill bit or a cone of a roller cone earth-boring drill bit). At least partially formed earth-boring tools include a metal or metal alloy bonding agent at an interface between two or more elements, at least one of which may comprise a green or brown structure.Type: GrantFiled: July 31, 2007Date of Patent: September 18, 2012Assignee: Baker Hughes IncorporatedInventors: Nicholas J.

Patent number: 8268234Abstract: New cermets with improved properties and applications are provided. These new cermets have lower density and/or higher hardness than B4C cermet. By incorporating other new ceramics into B4C powders or as a substitute for B4C, lower densities and/or higher hardness cermets result. The ceramic powders have much finer particle size than those previously used which significantly reduces grain size of the cermet microstructure and improves the cermet properties.Type: GrantFiled: January 28, 2011Date of Patent: September 18, 2012Assignee: Lawrence Livermore National Security, LLCInventor: Richard Lee Landingham

Publication number: 20120189484Abstract: A molding is produced with a disk-shaped or plate-shaped basic body having a large number of knob-like and/or web-like elevations which merge into the basic body with inclined side surfaces. The molding is produced by pressing and sintering powdery raw materials close to the final shape. First, the boundary surfaces of the basic body are pressed to final shape as far as the transition regions of the elevations and the elevations are pressed to an oversize. The projection height of the elevations from the basic body is greater than the projection height in the finally pressed state. Their side surfaces form an angle of inclination in the range from 90°-150° with the respectively adjacent boundary surface of the basic body. Then the elevations are pressed to near final shape while the angle of inclination is enlarged to a greater value.Type: ApplicationFiled: March 30, 2012Publication date: July 26, 2012Applicant: PLANSEE SEInventors: Gebhard Zobl, Wolfgang Glatz, Wolfgang Kraussler, Robert Oberbreyer
