Abstract: Disclosed is a method for producing a vehicle wheel with a connection between a wheel rim and a wheel disc in which the wheel disc is connected to the wheel rim by means of at least one connecting element that is guided through a through-hole of the rim base and is joined in the wheel disc. After the joining of the connecting element in the wheel disc a portion of the head of the connecting element projects beyond the rim base on the outer side of the rim. Subsequently the head of the connecting element is at least partially removed.

A joint arrangement suitable for repairing a void in at least one element, wherein said at least one element has a first surface and a second surface, wherein the thickness of the at least one element is at least 10 mm, further comprising two or more insert elements, each of said two or more insert elements each being friction stir welded at their abutted surfaces to said at least one element, characterized wherein said at least one element comprises at least one recess portion, wherein a Friction Stir Weld is caused from the direction of said first surface.

Abstract: Casting methods and articles are disclosed wherein a molten first material is introduced into a mold which distributes the first material to form a first region of the article where it is subjected to a first condition suitable for growing a first grain structure, forming the first region of the article. A molten second material, compositionally distinct from the first material, is introduced into the mold to form a second region of the article. A hybridized material is formed by intermixing a first portion of the second material with the second portion of the first material. A second portion of the second material is subjected to a second condition suitable for growing a second grain structure distinct from the first grain structure, forming the second region of the article. The first region and the second region are integrally formed as a single, continuous article with a hybridized region formed between.

Abstract: A hollow-cast casting is provided, which includes at least one core opening that is caused by the production technique and which has a closure device that closes the core opening. The closure device can be inserted into the core opening axially in relation to the core opening and provides at least one surface region which, in axial projection in relation to the core opening, can be made to abut a surface region of the casting that is facing toward the casting. The surface region lies radially outside a cross-sectional area predetermined by the core opening.

Abstract: The present invention relates to materials, methods and apparatuses for performing imprint lithography using amorphous metallic materials. The amorphous metallic materials can be employed as imprint media and thermoplastic forming processes are applied during the pattern transfer procedure to produce micron scale and nanoscale patterns in the amorphous metallic layer. The pattern transfer is in the form of direct mask embossing or through a serial nano-indentation process. A rewriting process is also disclosed, which involves an erasing mechanism that is accomplished by means of a second thermoplastic forming process. The amorphous metallic materials may also be used directly as an embossing mold in imprint lithography to allow high volume imprint nano-manufacturing. This invention also comprises of a method of smoothening surfaces under the action of the surface tension alone.

Abstract: A cast component having localized areas of improved physical properties is disclosed. The component may initially be produced having a void portion in a predetermined area requiring improved physical properties. A second molten material may be added to the void portion such that it chemically bonds to the void portion. The component may then be finished such to a final shape with a localized area of improved physical properties.

Abstract: A process for repairing one or more worn inlet ports on an interior or exterior surface of an extruder die wherein each inlet port provides an opening into an extrusion channel. The worn inlet port has a funnel shape and a diameter greater than that of the extrusion channel. The worn inlet port is repaired by placing a fused silicon oxide insert into one or more extrusion channels so that an external surface of the insert engages the interior surface of the extrusion channel, thereby forming a pocket around the insert between the circumference or perimeter of the worn inlet port and the external surface of the insert. The pocket is filled with molten metal, and the insert prevents the molten metal from entering the extrusion channel. When the molten metal hardens the inserts are removed. New inlet ports are thereby formed having the same diameter as the extrusion channels.

Abstract: Disclosed is: (i) a cap for servicing a molding-system valve, and (ii) a method of a cap for servicing a molding-system valve, amongst other things.

Abstract: A hollow airfoil is fabricated by providing a casting mold assembly including a casting mold, a casting core, and a standoff spacer that prevents the casting core from contacting the casting mold to define a casting space. A first nickel-base superalloy is cast into the casting space and solidified to form the hollow airfoil. The presence of a through-hole extending through a wall of the hollow airfoil is identified, and the through-hole is closed by welding using a second nickel-base superalloy, without using any freestanding closure element.

Abstract: A side outer panel that is a body panel is separated into a body front side section (10), a body rear side section (11) and a side sill section (12). These separated repair parts are produced using local molds produced to correspond to each part. The local molds are produced only when the mold cost is lower than the lost material cost in the case where the divided repair parts are produced by directly cutting from the body panel.

Abstract: A method of making or reconstituting tooling to be used in the processing of high temperature molten material comprises machining an undercut in the tooling surface which terminates at a shoulder and provides an inset barrier receiving surface; a chemical barrier providing interface coating system to which a ceramic-based material will fuse, is fused over the undercut receiving surface. Then a thermally-insulative ceramic-based coating is fused to the interface system to fill the undercut and merge with the tooling surface.

Abstract: An undersize repair region of a gas turbine engine stationary shroud is repaired with a sufficient mass of a repair material. The repair material includes a first fraction of a first powder of a first alloy component, and a second fraction of a second powder of a second alloy component. The first alloy component and the second alloy component have different solidus temperatures. The repair material is placed in the repair region. The repair material and the repair region are heated to melt the repair material but not the repair region, and thereafter the repair material and the repair region are cooled to solidify the repair material.

Abstract: A roll for use in a continuous casting machine includes a roll body that is constructed and arranged to be mounted for rotation in a guide segment area of a continuous casting machine, and a generally cylindrical outer surface on the roll body. Preferably, the outer surface is fabricated at least in part from an age-hardenable nickel-based alloy that includes, in weight percent, up to 0.3% carbon, about 5% to about 12% chromium, and about 10% to about 30% molybdenum. The roll exhibits superior high temperature strength and stability, low thermal expansion, and superior oxidation resistance at temperatures that are typical during operation in a continuous casting machine. A process of making a metal casting using such a roll is also disclosed.

Abstract: A method for repairing a recess in an article surface comprises providing first and second metallic powders. The first powder has a first melting temperature and the second powder has a second melting temperature less than the first melting temperature. The first powder is disposed in the recess substantially to fill the recess at least to the article surface. The second powder is disposed over the first powder in an amount that will fill the recess at least to the article surface after melting and flowing the second powder into the recess. The powders are heated to a treatment temperature at least at the second melting temperature and less than the first melting temperature for a time sufficient to melt the second powder, to flow the second powder into the recess about the first powder, and to bond the second powder to a recess surface.
