  • Publication number: 20220168811
    Abstract: An alloy which consists of aluminum, titanium, scandium and zirconium with or without one, two or more further metals selected from hafnium, vanadium, niobium, chromium, molybdenum, silicon, iron, cobalt, nickel and calcium. The aluminum alloy is suitable for the additive manufacture of lightweight components for aircraft. In a first additive manufacturing step, such as laser melting by the L-PBF process (laser powder bed fusion), a lightweight component precursor is produced from a powder of the aluminum alloy of the invention, this precursor comprising titanium, scandium and zirconium in solid solution, as a result of rapid solidification of the laser melt. In a second step the lightweight component precursor is hardened by precipitation of secondary phases at 250 to 400° C. to give the lightweight component. 3D-printed lightweight components of high strength are obtained.

  • Patent number: 8778374
    Abstract: The invention relates to a bone formation agent of porous calcium phosphate having an isotropic sintered structure and, between the particles of the calcium phosphate, statistically distributed pores in a plurality of discrete size ranges. The bone formation agent has at least two, preferably three, discrete pore size distributions. Its porosity has an irregular geometric shape. The sintered particles of the calcium phosphate have a particle size smaller than 63 ?m with a d50 value in the range from 5 to 20 ?m. The interconnecting pore share in the overall porosity is limited to pore sizes less than 10 ?m. The bone formation agent can be used in the form of a granulate or shaped body for bone regeneration. In the case of granulates, the maximum pore diameters are matched to the granulate diameter. The invention relates also to a method of producing the bone formation agent.

  • Publication number: 20060096959
    Abstract: In a method for welding joint partners, a shaped piece that is extruded out of a welding filler material is arranged between joint partners, which are to be connected, in such a way that it is in contact with both joint partners. The section of the shaped piece is matched to the geometry of at least one of the joint partners, so that before welding, the shaped piece is connected to the at least one joint partner in a form-locking manner. Subsequently, the joint partners are welded together along the shaped piece.

  • Patent number: 6861156
    Abstract: A metal fiber-reinforced composite material can be produced by providing metal layers and reinforcing layers disposed alternately into a sandwich structure, the reinforcing layers containing fibers of a high-strength metallic material, which are disposed in the form of a loose structure between the metal layers, in order to create a material excess of fibers in the reinforcing layers, the sandwich structure being bonded by a thermomechanical process in such a manner, that the fibers are lengthened because of the excess of material, the sandwich structure being bonded.

  • Patent number: 6793118
    Abstract: A laser-assisted friction stir welding method for joining workpieces, that includes the step of providing a side face for each workpiece between first and second workpiece surfaces, each side face shaped such that, in a pressed-together condition, the side faces touch each other at the second workpiece surface and are spaced from each other in a middle region of the side faces so that a gap exists between the side faces at the first workpiece surface. The method also includes pressing together the side faces so as to form a joint area, and advancing a welding probe, while the probe is in rotary motion, along the joint area at the first workpiece surface and irradiating workpiece material located in front of the welding probe using laser radiation so as to plasticize the workpiece material along the joint area. The method also includes removing the welding probe from the joint area before the workpiece material completely solidifies.

  • Patent number: 6772935
    Abstract: A method for friction stir welding using liquid cooling. The method includes the steps of moving a pin tool across a welding location, spraying a cooling liquid in a localized manner from a cooling ring moving with the pin tool onto a trailing region and onto lateral regions of the welding location adjacent to the pin tool, and blowing cooling gas from a gas jet moving with the pin tool from a front of the pin tool against the pin tool and against the cooling liquid emerging from the cooling ring. In addition, a friction stir welding and cooling device includes a pin tool configured to move across a welding location and a cooling ring at least partially encircling the pin tool. The cooling ring is configured to move simultaneously with the pin tool across the welding location and includes a plurality of nozzles configured to spray a cooling liquid.

  • Publication number: 20030111515
    Abstract: The aim of the invention is to achieve a method for friction stir welding, whereby the welding of alloys with high oxygen affinity and/or high plasticisation energy is possible and the heat flux from the welding location is easily controlled. Said aim is achieved whereby the cooling liquid from a cooling ring (2), moving with the pin tool (1), is physically limited to being sprayed on the trailing region and the lateral region of the welding location adjacent to the pin tool (1). Additionally, a gas jet (3) moving with the pin tool (1), blows cooling gas from the front against the pin tool (1) and against the cooling water escaping from the cooling ring (2).

  • Patent number: 6543721
    Abstract: A stressed-skin component is made of metal including a skinplate and integrated stiffening profiles, which skin component apart from the required rigidity also provides adequate crack advance behaviour and retained strength behaviour. The stiffening profiles in the base area comprise a thicker region of a profile base thickness; the thicker region having a reduced connection thickness at the connection with the skinplate. The profile base thickness is at least twice the connection thickness.
