The present invention provides an iron-aluminum-based plated steel sheet, and a manufacturing method therefor, the iron-aluminum-based plated steel sheet comprising a base steel sheet and a plated layer formed on the surface of the base steel sheet, wherein the alloy plated layer comprises: a diffusion layer comprising an Fe—Al-based intermetallic compound having a cubic structure; and an alloyed layer formed on the diffusion layer and composed of an alloy phase differing from that of the cubic structure, the thickness of the diffusion layer is 3-20 μm, and the thickness of the diffusion layer is greater than 50% of the total thickness of the plated layer.

A method of manufacturing a steel sheet plated with an Al—Fe alloy for hot forming. The method includes: aluminum-plating and coiling a base steel sheet to obtain an aluminum-plated steel sheet, where an amount of the aluminum-plating is 30 to 200 g/m.sup.2 based on one surface of the base steel sheet, and tension in the coiling is 0.5 to 5 kg/mm.sup.2; after the aluminum-plating, performing cooling to 250° C. at a rate of 20° C./sec or less; annealing the aluminum-plated steel sheet to obtain the steel sheet plated with the Al—Fe alloy; and cooling the steel sheet plated with the Al—Fe alloy. The annealing is carried out for 30 minutes to 50 hours within a heating temperature range of 550 to 750° C. in a batch annealing furnace.

An aluminum alloy brazing sheet has a 3XXX, 1XXX or 6XXX core, an interliner and a 4XXX brazing layer without added Mg. The interliner has Bi and Mg, the magnesium migrating to the surface of the brazing sheet during brazing and reducing the aluminum oxide to facilitate brazing without flux in a controlled inert atmosphere with reduced oxygen.

An adhesive composition including an epoxy-based adhesive polymer and a phosphorous element-containing compound; a process for making the adhesive composition; a process for increasing the corrosion resistance property of the adhesive composition; and a process for bonding a metal substrate with the adhesive composition to increase the corrosion resistance of the substrate by at least 40 percent.

To suppress occurrence of stress corrosion cracking in a weld due to tensile residual stress generated in a web or a middle rib in case of bend forming of an aluminum alloy extrusion having the weld on the web or/and the middle rib. In bend forming of the aluminum alloy extrusion, a peak position of tensile residual stress generated in the middle rib exists in a region other than the vicinity of the weld. Since the peak position is away from the weld by a distance, tensile residual stress in the weld is reduced, making it possible to suppress occurrence of stress corrosion cracking.

An aluminum alloy brazing sheet used for brazing of an aluminum material in an inert gas atmosphere or in vacuum is formed of a two-layer material in which a brazing material and a core material are stacked. The core material is formed of an aluminum alloy and has a grain size of 20 to 300 μm, and the aluminum alloy contains Mn of 0.50 to 2.00 mass %, Mg of 0.40 to 2.00 mass %. Si of 1.50 mass % or less, Fe of 1.00 mass % or less, and Ti of 0.10 to 0.30 mass %, with the balance being aluminum and inevitable impurities. The brazing material is formed of an aluminum alloy containing Si of 4.00 to 13.00 mass % with the balance being aluminum and inevitable impurities. In a drop-type fluidity test, a ratio α (α=K.sub.a/K.sub.b) of a fluid coefficient K.sub.a is 0.50 or more.
