摘要： Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

摘要： The invention concerns a process to manufacture a flat-rolled product, notably for the aeronautic industry containing aluminum alloy, in which, notably a flattening and/or stretching is performed with a cumulated deformation of at least 0.5% and less than 3%, and a short heat-treatment is performed in which the sheet reaches a temperature between 130° C. and 170° C. for a period of 0.1 to 13 hours. The invention notably makes it possible to simplify the forming process of fuselage skins and to improve the balance between static mechanical strength properties and damage tolerance properties.

摘要： Described herein are 6xxx series aluminum alloys with unexpected properties and novel methods of producing such aluminum alloys. The aluminum alloys are highly formable and exhibit high strength. The alloys are produced by continuous casting and can be hot rolled to a final gauge and/or a final temper. The alloys can be used in automotive, transportation, industrial, and electronics applications, just to name a few.

摘要： Method of forming a component of complex shape from an Al-alloy sheet or a Mg-alloy sheet. The method includes the steps of: a) heating the sheet to a temperature below the solution heat treatment (SHT) temperature for the alloy; b) forming the heated sheet between heated dies into or towards the complex shape; c) heating the sheet to at least its SHT temperature and substantially maintaining that temperature until SHT has been completed; and d) quenching the solution heat treated sheet between cold dies and at the same time completing the forming into the complex shape or maintaining that shape.

摘要： A method for producing an aluminum-copper alloy from a lithium ion secondary battery includes supplying an aluminum source and a copper source derived from an aluminum-based positive electrode collector and a copper-based negative electrode collector, respectively, into a furnace, and melting the aluminum source and the copper source in a way that produces an alloy substantially free of a lithium component.
