    Abstract: An apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool in combination with an electromagnetic force generated by the interaction of the applied current with a transverse magnetic field. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample or charge of metallic glass alloy to a predetermined “process temperature” between the glass transition temperature of the amorphous metal and the equilibrium melting point of the alloy in a time scale of several milliseconds or less, at which point the interaction between the electric field and the magnetic field generates a force capable of shaping the heated sample into a high quality amorphous bulk article via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, and blow molding in a time scale of less than one second.

  • Patent number: 6852181
    Abstract: A method for cold forming a flattened, end-threaded rod into a U-bolt answers the need for high-strength steel rods that can be bent into flattened U-bolts by spring and suspension repair facilities or the like. By controlling the amount of work put into the end-threaded flattened rod during bending, it is possible to manufacture a flattened, end-threaded rod from a high-strength steel that can be successfully cold bent into a U-bolt. The amount or degree of flattening and the radius of the U-bolt are variables which applicant controls to successfully cold bend a high-strength steel flattened rod into a U-bolt. Therefore, the spring and suspension repair facility avoids the need to heat the flattened rods for warm forming and, instead, can maintain an inventory of end-threaded and flattened rods for cold forming into flattened U-bolt comply with OEM designs when modifying or repairing vehicles.

  • Patent number: 6534194
    Abstract: In accordance with the invention a reactive multilayer foil is fabricated by providing an assembly (stack or multilayer) of reactive layers, inserting the assembly into a jacket, deforming the jacketed assembly to reduce its cross sectional area, flattening the jacketed assembly into a sheet, and then removing the jacket. Advantageously, the assembly is wound into a cylinder before insertion into the jacket, and the jacketed assembly is cooled to a temperature below 100° C. during deforming. The resulting multilayer foil is advantageous as a freestanding reactive foil for use in bonding, ignition or propulsion.

  • Patent number: 6329079
    Abstract: A tube for a cracker unit in which ethylene is produced withstands, without oxidizing or losing its strength, the elevated temperatures required to effect cracking, yet retards coking. The tube has a shell formed from stainless steel or high nickel alloy and a liner formed from an iron-aluminum alloy. The liner retards the deposit of carbon and its build up known as coking. To form the tube, a high alloy ingot is bored to provide a bore that extends through its center. Then a weld overlay is applied to surface of the bore, with the overlay being derived from a weld metal containing at least 16% aluminum and the balance essentially iron. Thereafter, the ingot is heated to its hot working temperature and extruded through sets of opposed rollers, with the direction of advance being in the direction of the bore. The extruding transforms the ingot into a lined tube.

  • Patent number: 6250127
    Abstract: A process for low cost manufacturing light-weight, heat-dissipating structures such as heatsinks, heat spreaders, and covers or lids for microelectronic components such as flip-chip integrated circuits from difficult-to-machine metal matrix composites such as aluminum silicon carbide (generically referred to as “Al—SiC” or “AlSiC”). The process involves selecting a mass produced quantity of Al—SiC material, forming that material into a thin ribbon, then stamping/coining the ribbon into the structures. The ribbon can be formed by extruding a thin strip from a billet of the Al—SiC material, then plurally rolling it. In this way, commonly available AlSiC composites manufactured in high volume for use in other applications such as cast automotive parts may be used.

  • Patent number: 6163961
    Abstract: A method of making a multi-layer plain bearing comprises roll-bonding a relatively soft aluminum-tin alloy to a harder aluminum-based bearing substrate and then roll-bonding the composite to a steel backing. Following heat treatment conventional for reticulation of the aluminum-tin alloy the surface is machined to give a precise overall bearing thickness of which the aluminum-tin overlay is in the range of 0.01-0.10 mm, typical of an overlay but having greater fatigue strength and war resistance than conventional electro-deposited materials. Alternatively, the overlay substrate and backing strips may be roll-bonded simultaneously.

  • Patent number: 6153316
    Abstract: Non-directional and diffuse reflecting photometric properties may be imbued to a metal sheet stock, particularly aluminum alloy sheet stock, by directly creating a textured surface on one or more surfaces of the sheet stock through mechanical texturing with at least one textured work roll in a cold roll reducing mill. A textured metal sheet surface thus produced is characterized by having over its entire surface randomly formed imbricated depressions transversely arranged, such that each depression has a substantially transverse width dimension relative to a longitudinal axis of the sheet and a longitudinal dimension greater than its width. The depressions formed are substantially equiaxial. Surface properties of both the textured work roll and the textured metal sheet may be controlled. The metal sheet stock are subjected to finishing steps such as chemical brightening and anodizing, or organic coating to provide lighting sheets with high total reflectance.

  • Patent number: 5896642
    Abstract: A metallic article is fabricated by providing a die and a piece of a bulk-solidifying amorphous metallic alloy having a glass transition temperature. The bulk-solidifying amorphous metallic alloy is heated to a forming temperature of from about 0.75 T.sub.g to about 1.2 T.sub.g and forced into the die cavity at the forming temperature under an external pressure of from about 260 to about 40,000 pounds per square inch, thereby deforming the piece of the bulk-solidifying amorphous metallic alloy to a formed shape that fills the die cavity. Preferably, a pressure is applied to the piece of the bulk-solidifying amorphous metallic alloy as it is heated, and the heating rate is at least about 0.1.degree. C. per second. The die may be a male die or a female die. When the die has a re-entrant comer therein, the formed shape of the bulk-solidifying amorphous metallic alloy is mechanically locked to the die.

    Abstract: A hollow extruding die for extruding a hollow section of a zinc-containing aluminum alloy is provided. The die is protected from cracks and has an extended life, without requiring any substantial structural changes to the die. In the die mandrel of the die a mandrel is connected by bridges with an outer cylindrical member. The bridges have a tapered projection facing toward the mandrel. A 3 mm thick coating composed of a nickel alloy is bonded on the surface of the projection by padding the welding material. Instead of coating the bridges, a covering can be attached to the surface of the bridges. To receive the covering, an engaging groove extends from the root of the mandrel and along the surface of the bridges to the outer cylindrical member of the die mandrel. The covering is composed of the same steel material as that of the die or of the nickel alloy. The covering has a through hole for receiving the mandrel formed on the base.
