A tailored blank for hot stamping includes a welded portion formed by butt-welding a first aluminum-plated steel sheet and a second aluminum-plated steel sheet, an Average Al concentration of a weld metal in the welded portion is in a range of 0.3 mass % to 1.5 mass %, an Ac.sub.3 point of the weld metal is 1250 C. or lower, and furthermore, an aluminum layer formed during the butt-welding is present on a surface of the welded portion.

A metal foil that has a carrier and a preparation method thereof. The metal foil with a carrier comprises a carrier layer, a barrier layer, a striping layer, and a metal foil layer. The carrier layer, the barrier layer, the striping lay, and the metal foil layer are sequentially stacked, or the carrier layer, the striping layer, the barrier layer, and the metal foil layer are sequentially stacked. The diffusion depth of the carrier layer to the metal foil layer is less than or equal to 3 m and the diffusion depth of the metal foil layer toward the carrier layer is less than or equal to 3 m at a temperature of 20-400 C. By setting the barrier layer, the carrier layer and the metal foil layer are prevented from diffusing mutually to cause bonding at a high temperature, so that the carrier layer and the metal foil layer are easy to peel off.

An apparatus, material and method for forming a brazing sheet has a high strength core bonded with corrosion protection layer on the coolant side and/or layers on both airside and coolant side. The material enables heat exchanger components, such as tube, header, plate, etc., for applications, such as automotive heat exchangers, that require high fatigue life as well as high service life in a corrosive environment.

A method of producing a seamless, composite tubular product includes centrifugally casting a metal or alloy into a tubular workpiece having an inner diameter. The method then centrifugally casts a corrosion resistant alloy in the inner diameter of the tubular workpiece to form a composite tubular workpiece having an inner diameter and an outer diameter. The inner diameter of the composite tubular workpiece is formed of the corrosion resistant alloy, and the outer diameter is formed of the metal or alloy. The method then subjects the composite tubular workpiece to at least about a 25% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process. The metal forming process includes radial forging, rolling, pilgering, and/or flowforming.

The present invention has as its object to inhibit fracture due to a HAZ softened part in substantially circular laser lap welding taking the place of resistance spot welding for joining a superposed plurality of steel sheets including a high strength steel sheet.

To solve this problem, the inventors discovered lap welding comprising superposing a plurality of steel sheets and firing a laser to form a substantially circular laser weld (1), which lap welding firing the laser in a straight line through an outer edge of the substantially circular laser weld (1) so as to form a hardened part (8) at the steel sheets and thereby suppressing fracture arising from the HAZ softened part.

A kind of aluminum alloy and corresponding heat treatment process applied to manufacturing aluminum/steel cladding plates which are resistant to high temperature brazing belong to alloy materials technology field. In the aluminum/steel cladding plates, the aluminum part was alloyed with 0.76%0.78% Si and 0.0550.10% Er in weight percent and the rest was Al and some unavoidable impurity. The Steel part was 08Al steel. After cladding cold rolling with deformation of 55%2%, the aluminum/steel cladding plates were annealed at 510535 C. for different times. Then simulated brazing process was performed to optimize the range of annealing time and temperature. The so produced Al/St cladding plates could not only effectively solve the low interface strength in Al/St cladding plates, but also meet the mechanical properties which were necessary for further processing of Al/St cladding plates. It was provided a kind of aluminum alloy and corresponding heat treatment process which could effectively solve the low bonding strength under the condition of high temperature brazing because of the existence of brittle FeAl phases.

A tailored welded blank produced from at least two blank parts, where at least one is a press-hardenable manganese-boron steel and at least one has a coating of aluminum or an aluminum-based alloy. The parts are welded by laser-beam welding or hybrid laser/gas-metal-arc welding, while retaining the coating, using shielding gas and a filler wire having in % by weight: C: 0.41 to 0.9; Si: 0.4 to 4; Mn: 0.4 to 3; optionally Cr: 0 to 10; and with optional alloying of one or more of: Mo: 0.01 to 1.0; B: 0.0008 to 0.0040; Ti: 2.5B<=Ti<=5B; V: 0.01 to 0.4; Nb: 0.01 to 0.2; W: 0.01 to 0.2; the remainder Fe and unavoidable impurities.
