  • Patent number: 11161590
    Abstract: An exterior panel for hypersonic transport vehicles is formed of a superplastic metal alloy such as titanium for accommodating high thermal stresses of hypersonic flight. The exterior panel, designed as re-usable on such transport vehicles, includes an exterior skin configured for atmospheric exposure, and an interior skin configured for attachment to structural frame members of the transport vehicles. An intermediate skin is situated between a pair of multicellular cores; each multicellular core is sandwiched between the exterior and interior skins, one core being situated between the exterior and intermediate skins, while the other is situated between the intermediate and interior skins. An airflow channel (AFC) extends through at least one of the multicellular cores for cooling of the exterior panel. Each multicellular core is superplastic formed and diffusion bonded to the other, as well as to its respective pair of skins to form an exterior panel having a unified structure.

  • Patent number: 11052445
    Abstract: A method of forming a part includes extruding a billet through a die, forming a round, closed geometry tube from the billet, and hydroforming the round, closed geometry tube. The extrusion die contains an orifice with a central mandrel, a plurality of bridges, and a corresponding plurality of portholes between the bridges. A spacing of the bridges around the mandrel is non-equiangular. As a result, the round, closed geometry tube has non-equiangular welds after emerging from the die.

  • Patent number: 10995398
    Abstract: A preferred embodiment is an uncoated, biodegradable stent. The stent has a filigree structure of magnesium alloy struts. The struts of the supporting structure are arranged to permit a compressed form for introduction into the body and to permit an expanded form at the site of the application within a vessel. The magnesium alloy struts are formed of a corrodible magnesium alloy. The magnesium alloy is formed from high-purity vacuum distilled magnesium containing impurities, which promote electrochemical potential differences and/or the formation of precipitations and/or intermetallic phases. The impurities are such that the struts of the stent have a tensile strength of >275 MPa a yield point of >200 MPa, a yield ratio of <0.8, a difference between tensile strength and yield point of >50 MPa.

    Abstract: In one aspect, the invention is directed to a half-cradle for use in a vehicle frame, comprising a cast end member formed from a first material and first and second tubular cross-member stubs extending from the cast end member. The first and second tubular cross-member stubs are made from a second material. Each of the stubs has an end buried in the cast end member, wherein the buried end is uncapped. Each of the tubular cross-member stubs has an interior that is configured to sealingly receive a core for use in preventing the filling of the stub with molten first material during casting of the cast end member.

  • Publication number: 20120263967
    Abstract: A blank tube for cold drawing is used for the production of a longer-length, small-diameter tube such as a heat-transfer tube for steam generation in nuclear power facilities, wherein the blank tube will not cause scoring and chattering vibration in a drawing process. The blank tube is used to produce a cold drawn tube through cold drawing of the blank tube. The average surface roughness Ra (ANSI B46.1) of the inner surface of blank tube before drawing satisfies the condition: 0.10 ?m?Ra?1.00 ?m in the case of a blank tube for cold drawing for use in an oil-lubricated drawing. In particular, the surface roughness Ra satisfies the condition: 0.10 ?m?Ra?0.50 ?m in the case of a blank tube for use in a high-pressure lubrication drawing and made of an austenitic alloy for use in a heat-transfer tube for a steam generator.

  • Publication number: 20120251836
    Abstract: We describe a lattice part made of metal and a method for producing a lattice part made of metal or a metal alloy. The lattice has a thickness of less than 1 mm at a size of the gaps of less than 50 mm2. The lattice (5) comprises a connection made of knots, and perpendicular to the lattice surface has lattice bars and lattice knots of the same thickness. A method for the production of a lattice part made of metal, particularly made of light alloy, is characterized by a primary shaping process according to DIN 8580, wherein a mold is formed in the first step, a primary material is introduced in the mold cavity in the second step, the part is removed from the mold in the third step, and the finishing of the metallic lattice part is carried out in the fourth step.

  • Publication number: 20120244372
    Abstract: In a method for producing hot-rolled sections of steel with a rectangular or square cross-section, a substantially round pipe blank produced seamlessly by hot rolling or cold finished and welded and having a defined nominal outside diameter is initially produced and then formed at a forming temperature into a hollow section having the required cross-section, with visible edges C1 and C2 of the hollow section having a value ?1.5×t (t=wall thickness). The pipe blank has a nominal outer diameter determined from a reduction ratio of the pipe blank to be achieved and the hollow section dimensions to be achieved, wherein the reduction ration lies within a range of ?2% to ?13% and is determined according to the following formula: Reduction ratio R[%]=[(2×(H+B))??×D]×100%/[2×(H+B)].

  • Patent number: 8273117
    Abstract: Metallic stents which have a randomly oriented microstructure, and possess quasi-isotropic mechanical and physical properties are disclosed. The novel stents can be “tailor-made” to mimic the geometry of the blood vessel(s) at the deployment site and can be designed to treat coronary artery disease at the point where blood vessels branch. The metallic materials of choice are ductile, corrosion resistant and exhibit little crystallographic texture. The novel stents can be produced from a metallic precursor which is quasi-isotropic and exhibits little texture by processing means, such as machining, which do not reintroduce texture. Alternatively, quasi-isotropic and low texture stents are achieved by suitable post-processing of conventionally fabricated stent materials.

  • Patent number: 8202646
    Abstract: A battery case is made by cutting from a blank case of a bottomed cylindrical battery case having an unwanted portion at an opening portion the unwanted portion from the case wall in the circumferential direction by a blade. The cutting of the case wall is performed so as to render a cutting-end portion higher than a cutting-start portion. Thus, re-cutting of the cutting-start portion by the blade after it has already completed one rotation can be avoided. As a result, the generation of thread-like chips from re-cutting of the cut surface can be avoided.

  • Publication number: 20120121923
    Abstract: Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The CTE of the fine-grained metallic coating is matched to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.
