The reinforcement filaments 1 each mainly contain one or more metals selected from the group consisting of Nb, Ta, V, W, Mo, Fe, and Hf, an alloy consisting of two or more metals selected from the aforementioned group, or an alloy consisting of copper and one or more metals selected from the aforementioned group.

Problem There is proposed an innovative cross-sectional structure, with an idea contrary to the conventional one, utilizing the non-reactivity between Cu and Ta (or between Ag and Nb, Ta) in a high-temperature short-time heat treatment, thus achieving (1) the suppression of the low magnetic-field instability, (2) excellent wire drawability of a precursor wire, and (3) the reduction of the cost required for the incorporation of a stabilizer. Means for Resolution There is proposed a structure having an assembly of a plurality of single wires, wherein the assembly is covered with an outer cover (skin) formed from Nb or Ta, wherein each of the single wires has an Nb/Al composite filament region which is formed from a composite of Nb and Al mixed in an Nb:Al molar ratio of 3:1, and which is covered with a partition formed from Nb or Ta, and further covered with an interfilamentary barrier formed from Cu or Ag disposed around the partition.

The present invention relates generally to jewelry articles comprising a substrate and a metallic, external coating.

A plated steel sheet (1) includes: a steel sheet (2); a pre-plating layer (3) on at least one surface of the steel sheet (2), the pre-plating layer (3) containing Al, Cu, In, Zn, Sn, or Sb, or any combination thereof; and a plating layer (4) of a ZnNi alloy on the pre-plating layer (3), a Ni content of the ZnNi alloy being 5 mass % to 15 mass %.

A composite metal foil and a method of manufacturing the same are provided. The composite metal foil includes at least a first metal layer and a second metal layer. The first metal layer is copper foil, nickel foil, stainless steel foil, or a combination thereof. The second metal layer is disposed on a surface of the first metal layer. A contact angle of a surface of the second metal layer to liquid lithium metal is lower than 90 degrees.

The present invention relates to a hybrid base plate and a manufacturing method therefor. Metal sheets of different materials having excellent thermal conductivity can be joined to have a thickness favorable for heat dissipation, and by arranging a metal sheet of a material with a low coefficient of thermal expansion between metal sheets with a high coefficient of thermal expansion, there is an effect of preventing warpage when manufacturing a large-area heat sink.
