    摘要： Lead alloy strip material (4, 6, 8) is roll bonded on one or both opposite face surfaces of a core strip material (2). The core material can be commercially pure titanium, austenitic stainless steel, low carbon steel, copper, aluminum, alloys thereof or other suitable metal that has sufficient ductility and that can provide desired attributes of stiffness and corrosion resistance to the composite. The lead alloy material is strengthened by the addition of less than approximately 1% of calcium or antimony and the core material is softened by fully annealing it prior to bonding. The several strips are reduced in thickness, preferably in approximately the same proportion, by at least 40% in the bonding pass to create a solid phase bond among the strips. The bonded composite is then rolled to final gauge and, for selected applications, is corrugated and cut to form panels (20, 22, 24) and etched to form pockets (8b) for pasting of active materials such as lead oxide for battery plates.

    摘要： This invention describes the roll bonding of Al and Ni-bearing Cu alloys to suitable substrates to produce self-brazing materials for the elevated temperature, aggressive environment application. The Al and Ni-bearing Cu alloy for the self-brazing layers can be obtained by cladding layers of elemental Ni and Al to Cu. The Al content in the self-brazing layers can be varied from 2 to 100%. The Ni content in the self-brazing Cu alloy can be varied from 10 to 100%. Additional alloying elements in the commercial Cu alloys such as Fe, Cr, Si, Mn, Sn and Zn are unavoidable. Trace elements in the commercial alloys such as Pb, Ag and As will also affect the brazing and shall be reduced.

    摘要： A method for cleaning thin gauge metal foil strip material using a plurality of wiper (12, 16, 20) and solvent application (14, 18) stages. The solvent used in the solvent application stages is an aliphatic petroleum type which is applied using low pressure to avoid atomization or separation of solvent components. The wipers of a first wiping station are made of a solid bar of polymer impregnated fiber material. The wipers of the second wiping station are spaced apart blades of urethane-based elastomer material.

    摘要： A method for producing titanium alloy brazing strips and the resulting brazing strips and/or foils. The method uses a cold-rolling process without heat treating to generate a titanium based multi-layer alloy strip or foil made up of discrete layers of titanium and an additional layer or layers of one or more metals, such as zirconium, nickel and/or copper, for example, or alloys thereof, with the layer of titanium roll bonded without heat treating to the layers of the additional metal(s). The resulting strip or foil can include, for example, Cu/Ti/Cu, Ni/Ti/Ni, Ni/Ti/Cu, Cu/Ni/Ti/Ni/Cu, Ni/Cu/Ti/Cu/Ni, Ni/Cu/Ni/Ti/Ni/Cu/Ni, Ni/Zr/Cu/Ti/Cu/Zr/Ni and Ni/Ti/Cu/Zr/Cu/Ti/Ni among other combinations. The resulting strip or foil can be used for brazing, creating an alloy of the weight percentage of the original materials.

    摘要： A FeCrAl alloy for catalytic converter substrates having excellent oxidation resistance and dimension stability at a medium high temperature, e.g. the temperature encountered by catalytic converter substrates in truck diesel engines, without necessary addition of extra Y, Hf, Zr, or rare earth elements beyond that inherently present in commercial stainless steel. A roll bonding and diffusion alloying annealing method is used for making such materials with the following two deviated paths. First, material in which layers of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a multilayer composite material. Such composite material is then further rolled to an intermediate foil gauge, cleaned, and then subjected to a thermal reaction to form a resulting uniform solid solution foil material followed by rolling to the final foil thickness. Alternatively, such composite material is further rolled to the final foil thickness, cleaned, and then subjected to a thermal in-situ reaction in the material after a honeycomb-like catalytic converter is made from the foil composite material. Both deviated approaches result in a uniform solid solution foil material.

    摘要： A manufacturing method of metal substrate catalytic converter and the resulting product. In this method, a multiple layer aluminum and ferritic stainless steel composite material is first made by roll-bonding and then further processed to a final foil thickness. The composite foils are then fabricated to a honeycomb-like converter with air flow channels. The converter is then thermally treated at a high temperature during a necessary converter fabrication process. The monolithic FeCrAl alloy is then obtained in the converter by in-situ diffusion alloying with pre-oxide film on the surfaces. The resulted material has improved oxidation resistance and thermal dimension stability at a high temperature.
