  • Patent number: 7896222
    Abstract: This invention discloses a method, using pure niobium as a transient liquid reactive braze material, for fabrication of cellular or honeycomb structures, wire space-frames or other sparse builtup structures or discrete articles using Nitinol (near equiatomic titanium-nickel alloy) and related shape-memory and superelastic alloys. Nitinol shape memory alloys (SMAs), acquired in a form such as corrugated sheet, discrete tubes or wires, may be joined together using the newly discovered technique. Pure niobium when brought into contact with Nitinol at elevated temperature, liquefies at temperatures below the melting point and flows readily into capillary spaces between the elements to be joined, thus forming a strong joint. A series of diagrams of the interface at various stages of brazing is illustrated by FIG. 10.

  • Patent number: 7770779
    Abstract: A guide wire includes a wire member having a first wire disposed on the distal side of the guide wire, and a second wire disposed on the proximal side from the first wire. The second wire is made from a material having an elastic modulus larger than that of the first wire. For example, the first wire is made from a superelastic alloy, and the second wire is made from a stainless steel. The first wire is joined to the second wire at a welded portion by welding. A coil is disposed on the distal side from the first wire. A cover layer is formed on the outer peripheral surface of the wire member in such a manner as to cover at least the welded portion. The cover layer is made from a material capable of reducing the friction of the cover layer, for example, a fluorocarbon resin or a hydrophilic material, to thereby improve the sliding performance of the guide wire. Such a guide wire is excellent in operationality and kink resistance.

  • Patent number: 7748598
    Abstract: A method for joining clad metal plates having a protective layer (27), e.g. titanium, and a substrate layer (28), e.g. carbon steel, includes firstly removing margins (29) of protective layer along edges of the clad metal plates to be joined. The substrate layers are then welded together to form an exposed substrate weld (31). Covering material (38) of the same type as the protective layer (27) is then located along the exposed substrate weld (31) to a level substantially flush with an outer surface of the protective layer (27). The substrate layer (28) is heated prior to welding the covering material so that the covering material is pre-stressed when cooled. The method may be used to fabricate reaction vessels having seams that do not stand proud of the remainder of the interior surface of the vessel. The low profile seams are less susceptible to erosion than has been the case in the past so that longer-life vessels can be produced.

  • Patent number: 7025248
    Abstract: The invention relates to a roll-bonded titanium sheet (6), a shaped component manufactured therefrom (10) and a method for manufacturing the titanium sheet (6) and the shaped component (10). In order to achieve a high-temperature-resistant shaped component (10), a titanium sheet (2) is roll-bonded at least on one side with aluminium foil (4) whose thickness (d) is small compared with the thickness (D) of the titanium sheet (2). As a result of heat treatment of the roll-bonded titanium sheet (6), the aluminium and titanium from the adjoining region are converted to an aluminium-titanium alloy. The outer titanium-aluminium-alloy layer of the titanium sheet (6) thus formed is converted by contact with oxygen into a titanium-aluminium-mixed oxide layer which gives the titanium sheet (6) good corrosion protection. The forming of the shaped component (10) preferably takes place before the heat treatment for alloy formation because the roll-bonded titanium sheet (6) is then still slightly deformable.

  • Patent number: 6732909
    Abstract: A backing plate of Ti for supporting a Ti sputtering target is formed of at least two components welded together. The backing plate is welded by interposing a Cu or Zr foil or powder between faces to be welded, and then heating the assembly to a reaction temperature high enough to melt one of the Ti and Cu or Zr to produce a liquid phase. The heating temperature is retained for a time long enough to permit diffusion of the Cu or Zr into the Ti to produce a liquid phase diffusion weld. By permitting diffusion to occur, a separate metallic compound is not produced at the welding face. In effect welding is accomplished without producing a welding face, whereby no interface exists in the finished weld. The resulting weld has a strength substantially equal to the strength of the Ti material, and very good welding qualities.

  • Patent number: 6410165
    Abstract: A welding method that enables the joining of at least two dissimilar, metallic alloys to form a weld that is free of cracks is disclosed. The method incorporates a pure (99.00% minimum by weight) nickel fill-wire, integrally assembled into the joint between the two alloyed metals to be joined. The alloys joined by this method are an iron-based, low expansivity, gamma-prime strengthened superalloy (i.e., Incoloy®) and a high carbon, powder metallurgical tool steel high in refractory metal alloying agents (i.e., CPM REX 20). Welding of the joint results in the formation of a nickel rich region within the weld, thus “inoculating” the weld against cracks. The weld joint formed by the method of the present invention can be used in the fabrication of a rotating anode bearing shaft assembly for use in an x-ray generating device.
