    Abstract: A monolithic, substantially hermetic joining or bonding of two or more aluminum nitride (“AlN”) ceramic components is made by promoting transient liquid phase sintering near the contact areas between the components. In a first approach, AlN particles are combined with a rare earth oxide sintering additive such as yttrium oxide (Y2O3) in a joining paste can be applied between the joining surfaces of fired ceramic preformed components prior to final firing to weld the components together. In a second approach, the additive is added to green mixture, and the components having different shrinkage aspect ratios are mated and cofired in an atmosphere containing a partial pressure of the additive. The additive encourages wetting and diffusion of the liquid phases present on the surfaces of ceramic interface particles in the contact areas during final firing. Such processes can be used to form complex ceramic structures such as a ceramic susceptor used in integrated circuit fabrication.

Each side wall spacer can have a tapered width and can be wedged between the plurality of conductor strands and an interior side wall of the cooling fluid box. Each middle spacer can have a tapered width and can be wedged between two columns of the conductor strands. The side wall spacers can taper in a direction opposite the taper of the middle spacers. In one embodiment, the cooling fluid box can move around the conductor strands. Each side wall spacer can be positioned against an interior surface of the cooling fluid box. Each middle spacer can be positioned between columns of conductor strands. The cooling fluid box can be withdrawn to a final position.

    Abstract: A welded joint improved in fatigue strength, a steel deck using the welded joint, and a process of producing the steel deck are provided. A steel deck 3 includes a steel plate 10 having a paving surface 11 on which a pavement is placed, and stiffeners 20 welded to a lower surface 12 of the steel plate opposite the paving surface. Single bevel grooves 22 are formed at respective edges 21 of each stiffener brought into contact with the steel plate, and a weld metal 30 is deposited in each single bevel groove 22. The weld metal is a low transformation-temperature welding material whose martensitic transformation occurs in a predetermined low temperature range. The groove angle ? of the single bevel grooves 22 and welding conditions are set based on data acquired so as to obtain a fixed dilution ratio of the weld metal 30 through control of penetration rate.

    Abstract: A shaft assembly includes a metallic portion and a ceramic portion. In a disclosed example, a ceramic shaft has a generally conical end that is at least partially received within a generally conical recess in one end of a metallic shaft. The recess has a first portion that has an inner surface that is received directly against a corresponding outer surface on a section of the ceramic shaft conical portion. A second portion of the recess is radially spaced from the ceramic shaft and provides a controlled gap within which a braze alloy is maintained. In one example, the second portion has an axial length that is more than twice a radial depth of the second portion. In another example, a transition surface between the first and second portions of the recess has a linear profile.

  • Patent number: 7104719
    Abstract: In a peripheral connecting region of two sheets including two overlapping flanges of the sheets, the sheets are connected to each other such that they cannot be displaced relative to each other. In order to be able to connect high-strength sheets or other sheets which can be difficult to weld to each other, the sheets are connected in the connecting region by a strip-shaped fastening element. The strip-shaped fastening element encloses the outer contour of the flanges and rests with some sections of its inner side on mutually remote surfaces of the two flanges. A method for producing the connecting region is also proposed.

  • Patent number: 6851886
    Abstract: A knee joint assembly for an agricultural implement or a vehicle includes a relatively short knee casting with an apertured end of rectangular cross section which is inserted in a mating steel knee tube. The apertures in the casting end align with beveled apertures in the side walls of the knee tube. Steel pins of length approximately equal to the spacing of the side walls are pressed into the casting through the beveled apertures. Groove welds then secure the steel pins to the knee tube. The casting is relatively small and does not require any welding. Inexpensive ductile iron and common steel tubes can be used for most or all of the assemblies on a machine. The apertured end of the casting includes concave walls to accommodate knee tube concavity and weld flash on the inside of the knee tube.

  • Patent number: 6543670
    Abstract: The present invention provides a structural assembly comprising a first workpiece and a second workpiece. The second workpiece at least partially underlies the first workpiece so as to define an interface therebetween. The assembly includes a friction stir weld joint joining the first and second workpieces. The assembly also includes an interface layer positioned between the first and second workpieces. The interface layer comprises a material having a melting temperature lower than the solidus temperatures of the first and second workpieces. The interface layer at least partially fills the interface proximate to the friction stir weld joint to thereby increase the strength and fracture toughness of the weld joint, as well as other mechanical and chemical properties, including resistance to crack growth and corrosion resistance.

  • Patent number: 6347901
    Abstract: A method and article of fabrication is described featuring a solder layer having a serpentine, interrupted, or interdigitated boundary. The non-planar design of the boundary layer increases the fatigue life of the solder joint by limiting the damage caused by micro-cracking. This irregularity of the solder boundary constrains the propagation of cracks by creating obstacles along the crack path, redirecting the crack away from the intermetallic layer, or by increasing the path along which the crack propagates.
