The present invention provides a process for manufacturing a metal strip having a metallic corrosion protection coating. The process includes making the metal strip pass through a bath of molten metal having between 2 and 8 wt. % aluminum, 0 to 5 wt. % magnesium and up to 0.3 wt. % addition elements, the balance being zinc and inevitable impurities. The bath is maintained at a temperature between 350 and 700 C. Nozzles wipe the coated metal strip spraying a gas on either side of the strip. The coating is cooled in a controlled manner until it has completely solidified. A metal strip and a metal part obtained by deformation of this strip are also provided.

A metamaterial thin film with plasmonic properties formed by depositing metallic films by atomic layer deposition onto a substrate to form a naturally occurring mosaic-like nanostructure having two-dimensional features with air gaps between the two-dimensional features. Due to the unique deposition nanostructure, plasmonic thin films of metal or highly conducting materials can be produced on any substrate, including fabrics and biological materials. In addition, these plasmonic materials can be used in conjunction with geometric patterns that may be used to create multiple resonance plasmonic metamaterials.

To produce pretinned strips of connectors for PV cells, a metal foil (30) is guided through a roll gap (46) of a rolling mill in which at least one work roll (48) has a surface with a corrugated structure with the result that a corrugated structure which has crests or peaks and troughs is embossed into at least one side of the metal foil (30), soldering tin in the form of solder preforms (54) is applied to the side of the metal foil (30) with the embossed corrugated structure, wherein the soldering flux necessary for pretinning has been applied in advance to the solder preforms or the metal foil, the solder preforms (54) are connected to the metal foil (30) or applied to it and melted on and the pretinned metal foil (30) with the embossed corrugated structure is separated into parallel ribbons. The solder preforms (54) are sufficiently thick for the corrugated structure to be at least full after the solder preforms (54) have been melted on.

A method for manufacturing an electric resistance welded steel tube including: forming a steel tube material into an almost cylindrical open pipe, the steel tube material being a steel sheet wherein Ti and N satisfy (N/14)<(Ti/47.9); forming an electric resistance welded steel tube by bonding ends of the open pipe to each other by induction resistance welding with heat input controlled so that the bond width is 30 to 65 m; heating the electric resistance welded steel tube to a temperature equal to or higher than the Ac.sub.3 transformation temperature; and diameter-reducing rolling the heated electric resistance welded steel tube with rolling reduction expressed by an outer diameter ratio greater than (125/the bond width before diameter-reducing rolling (m))100% such that the bond width is 25 m or less.

There are provided a magnesium alloy coil stock having good flatness and a method for producing the magnesium alloy coil stock, and a magnesium alloy structural member that uses the coil stock and a method for producing the magnesium alloy structural member. The coil stock is obtained by coiling a sheet composed of a magnesium alloy in a cylindrical shape, and the internal diameter of the coil stock is 1000 mm or less. The coil stock can be produced by rolling a cast material obtained by subjecting a magnesium alloy to continuous casting, subjecting the rolled sheet to warm leveling, and coiling the worked sheet in a cylindrical shape while the temperature just before coiling is decreased to 100 C. or less.

A metallic decorative part for a vehicle display device includes a substrate body molded from a synthetic resin, a metal thin film that is formed of metal and deposited on a surface of the substrate body, and a plurality of grooves deposited on a surface of the metal thin film in accordance with a shape of the surface of the substrate body. The grooves are formed so that a width is larger than 0 and equal to or smaller than 3.0 m, and a height is larger than 0 and equal to or smaller than 1.0 m. Accordingly, the metallic decorative part for a vehicle display device can properly secure a metallic texture recognized by a viewer with a configuration in which the metal thin film is deposited on the surface of the substrate body made of resin.

A hybrid structure comprises a metallic built-up sandwich structure, and a monolithic superplastic formed and diffusion bonded structure joined to the built-up sandwich structure.

Provided is a molding method for a plate-shaped workpiece including forming a concave portion (11) at one surface (1a) of a plate-shaped workpiece (1), and bending the plate-shaped workpiece (1) having the concave portion (11) such that the one surface (1a) becomes a concave surface and a rear surface (1b) thereof becomes a convex surface.

A self-aligning corner bead for fireproofing structural steel, having a strip of welded wire fabric cut to the appropriate width for the fireproofing thickness and bent longitudinally to form an obtuse V-shaped device is disclosed. A plastic nosing is installed along one edge. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the first wing of an obtuse V-shaped device through a lathe to the structural steel member utilizing pneumatic or screw type fasteners. The mesh structure of the second wing of the V-shaped device provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

A self-aligning, double wire corner bead for fireproofing structural steel along a plurality of surfaces, the corner bead having a single strip of welded wire fabric cut to a predetermined width for the fireproofing thickness and bent along a plurality of longitudinally extending lines, to provide a profile having a plurality of dihedral angles is disclosed. A nose is installed along two edges. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the corner bead through a lath to the structural steel member utilizing fasteners. The mesh of the corner bead provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.
