Provided is a method of manufacturing a composite metal material which includes a first metal member made of first metal and a second metal member made of second metal having a smaller linear expansion coefficient than first metal. The method includes in the following order: a metal member preparation step of preparing the first metal member made of first metal and a plurality of divided members made of second metal; an assembling step of assembling the respective metal members into an assembled body; and a bonding step of, by applying a first temperature and a first pressure which enable the respective metal materials to be bonded to each other to the assembled body, bonding the plurality of divided members to each other thus forming the second metal member and also of bonding the first metal member and the second metal member to each other.

Plate consisting of a steel substrate (1) and a precoat (2) consisting of a layer of intermetallic alloy (3) in contact with said substrate, topped by a layer of metal alloy (4), characterized in that, on at least one precoated face of said plate, an area (6) situated at the periphery of said plate has said metal alloy layer removed.

A method for producing a hot-pressed member includes heating a coated steel sheet, which includes, on a surface thereof, a ZnNi alloy coating layer containing 10% by mass or more and less than 13% by mass of Ni at a coating weight of over 50 g/m.sup.2 per side of the steel sheet, in a temperature region of an Ac.sub.3 transformation point to 1200 C. at an average heating rate of 12 C./second or more, and then hot-pressing the steel sheet.

Metal nanowires with uniform noble metal coatings are described. Two methods, galvanic exchange and direct deposition, are disclosed for the successful formation of the uniform noble metal coatings. Both the galvanic exchange reaction and the direct deposition method benefit from the inclusion of appropriately strong binding ligands to control or mediate the coating process to provide for the formation of a uniform coating. The noble metal coated nanowires are effective for the production of stable transparent conductive films, which may comprise a fused metal nanostructured network.

Billets and methods for manufacturing them are disclosed. The billets include a cladding member including an alloy selected from the group including stainless steel, nickel-chrome, nickel-copper, and copper-nickel alloys, and a steel body that is positioned so that it has an interface with the cladding member, the steel body having a formation in which the scavenging metal is located and elements being provided for separating the scavenging metal from the cladding member at the interface.

The invention relates to metallic substrates surface coated with a coating layer comprising a metal and an additive.
