摘要： A multi-element composite object composed from first, second, and third metal components is provided, wherein the first metal and the third metal are weld incompatible. The multi-element composite object includes a first component fabricated from a first metal. A second component, fabricated from a second metal, is brazed to the first component. A third component, fabricated from a third metal, is inertia welded to the second component. The first metal may be provided as a titanium alloy, e.g. a TiNi alloy. The second metal may be provided as low-carbon mild or alloy steel. The third metal may be provided as alloy steel, e.g., 9310 nickel alloy steel. In an embodiment, the multi-element composite object is a gear assembly, with the first element of the gear assembly object being a shaft and the third element of the gear assembly being a gear member with hardened teeth surfaces. The first and second components can be mechanically keyed together via an anti-rotational element. The anti-rotational element can be provided as a pin-in-groove arrangement or a twist-fit arrangement. A method of making a multi-metal composite object including a first component fabricated from a first metal, a second component fabricated from a second metal, and a third component fabricated from a third metal, wherein the first metal and the third metal are weld incompatible, is also disclosed. The first step of the method includes mechanically keying the first component to the second component. Next, the first component is brazed to the second component. Finally, the third component is welded to the second component. Where the first metal is a Ti alloy and the second metal is low-carbon steel, the step of brazing the first component to the second component can include brazing using a brazing material such as Ag and Cu. Where the third component is heat-treated steel, the assembly can be stress-relieved after inertia welding at a temperature sufficiently low so as not to degrade the heat-treated properties of the third component.

摘要： Methods for implementing production of an oxide superconductor joined member, excellent in electric current transmission performance, without a need of going through particularly complex steps, are provided. When joining together oxide superconductors by use of a solder composed of an oxide superconducting material, a finally solidified portion of the solder is positioned in a region where a transmission path of electric current flowing between oxide superconductor base materials as joined together is not obstructed by, for example, disposing the solder on a face of the oxide superconductor base materials, other than butting surfaces of the oxide superconductor base materials, so as to straddle both the base materials like bridge-building. Current flow is also not obstructed by, for example, shaping junction faces of the oxide superconductor base materials such that at least portions of the butting surfaces thereof are in the shape of sloped open faces, parting from each other. Further, an oxide superconductor joined member is made by joining the base materials with each other through the intermediary of an oxide superconductor, serving as a binder, disposed on at least a face of the base materials, other than butting surfaces thereof.

摘要： A method for brazing beryllium-aluminum alloy members to form a beryllium-aluminum alloy assembly and coating the beryllium-aluminum alloy assembly in which an aluminum-silicon based braze alloy is placed between the beryllium-aluminum members at the locations for forming braze joints. The aluminum-silicon based braze alloy is surrounded by a brazing flux comprising aluminum fluoride. The beryllium-aluminum alloy members and the aluminum-silicon based braze alloy are heated to form the beryllium-aluminum alloy assembly. Oxidized surfaces appearing on the beryllium-aluminum alloy members are removed. Thereupon, the beryllium-aluminum alloy assembly is coated by plasma deposition of alumina-titania powder.

摘要： A first aluminum brazing alloy for cold brazing, comprises 70 to 90% by weight of zinc and 0.05 to 5% by weight of titanium with the balance consisting of aluminum and impurities. A second aluminum brazing alloy for cold brazing, comprises 30 to 70% by weight of zinc, 1 to 7% by weight of silicon, and 0.05 to 5% by weight of titanium with the balance consisting of aluminum and impurities. Brazing alloys having these compositions have a low melting point and can well wet a base metal. Further, use of the above aluminum brazing alloy for cold brazing enables a low-melting aluminum material to be well brazed at 400 to 550° C.
