摘要： The invention relates to a method for re-melting coated aluminum alloy scrap comprising a step of supplying shredded coated aluminum alloy scrap, consisting of individual entities; a decoating step, a step of preparing a heel, a step of loading and melting the decoated scrap on the heel. The invention is characterized in that the scrap has a specific geometry wherein at least 50% of the individual entities of the shredded coated scrap has a fold ratio (R) of less than or equal to 0.6, wherein the fold ratio (R) of an individual entity is defined by: fold ratio=R=(unfolded area−folded area)/(unfolded area), wherein the folded area is the maximum area of the orthogonal projection of the individual entity onto a plane and the unfolded area is the total area of the same individual entity after it has been unfolded.

摘要： The invention concerns a method for improving aluminium alloy blank tensile yield stress and formability comprising the successive steps of: providing a 6xxx series aluminium alloy slab; optionally homogenizing the slab; hot rolling and optionally cold rolling the slab to obtain a sheet; solution heat treating and quenching the sheet; cold rolling the sheet with at least 20% cold work reduction; cutting the sheet into blanks; flash annealing a portion of the flange of the blanks at a temperature between 360° C. and 480° C. for a time sufficient to obtain recrystallization of the portion of the flange and cool to a temperature of less than 100° C. The improved blanks and the stamped product and painted stamped products obtained by the method of the invention are particularly useful for automotive applications because of their high strength.

摘要： A method for manufacturing a rolled product for automobile bodywork or body structure with an alloy containing Si: 0.75-1.10, Fe: max 0.4, Cu: 0.5-0.8, Mn: 0.1-0.4, Mg: 0.75-1, Ti: max 0.15, Cr: max 0.1 and V: max 0.1 is disclosed with several process steps from casting the ingot to forming and painting a car body part. The various possibilities of pre aging of the sheet as well as of the heat treatment of the part offer advantageous material properties in forming, material strength and low sensitivity to the bake hardening process which can vary depending in the part location in the car body.
