  • Publication number: 20230372986
    Abstract: A plate made of a rolled aluminum alloy and a method for producing said plate are disclosed. In order to achieve high strength values, it is proposed for the plate to have a partially recrystallized structure with a degree of recrystallization of less than 25%, wherein the non-recrystallized structure region of the structure is in the recovered state and has an average subgrain size of less than 10 ?m in the rolling direction.

  • Publication number: 20230042050
    Abstract: A sheet or strip made of a hardenable aluminum alloy, a vehicle part made therefrom, a use, and a method for producing the sheet or strip are disclosed. In order to insure a powerful paint bake response (PBR), it is proposed for the aluminum alloy to have from 4.0 to 5.5 wt % magnesium (Mg) and from 2.5 to 5.5 wt % zinc (Zn) and for it to be in the T4-FH state, wherein the wt % of magnesium (Mg) is greater than the wt % of zinc (Zn).

  • Publication number: 20220127708
    Abstract: A method for producing a sheet or strip from an aluminum alloy and a sheet, strip or molded part produced thereby are disclosed. A rough surface and stretcher strain marks can be avoided if the cold-rolled sheet or strip with a particular composition and microstructure is subjected to a heat treatment with a recrystallization annealing and a subsequent accelerated cooling.

  • Patent number: 10774409
    Abstract: An age-hardenable aluminum alloy on the basis of Al—Mg—Si, Al—Zn, Al—Zn—Mg or Al—Si—Mgv has precipitates caused by natural aging. The aluminum alloy has at least one alloy element, in addition to its main alloy element or in addition to its main alloy elements, which can be correlated with quenched-in empty spaces of the aluminum alloy, particularly reducing their mobility in the crystal lattice, at such a content less than 500, particularly less than 200 atomic ppm, that the aluminum alloy forms empty spaces essentially not correlated with these precipitates, in order to reduce the negative effect of natural aging of the aluminum alloy on its further artificial aging, by mobilization of these non-correlated empty spaces.

  • Publication number: 20190144977
    Abstract: A temperable aluminum alloy, an aluminum sheet or strip made of such an aluminum alloy, a molded part, and a method for producing such a molded part have been disclosed. In order—despite the low hot tempering temperature and high deformability—to enable achievement of the required yield strengths Rp0.2, a temperable aluminum alloy is proposed, containing from 2.5 to 3.5 wt. % zinc (Zn), from 0.5 to 1.5 wt. % magnesium (Mg), from 0.2 to 0.8 wt. % silicon (Si), from 0.005 to 0.2 wt. % tin (Sn) and/or indium (In) and/or cadmium (Cd), and optionally from 0 to 0.35 wt. % copper (Cu), from 0 to 0.3 wt. % silver (Ag), from 0 to 0.25 wt. % iron (Fe), from 0 to 0.12 wt. % manganese (Mn), from 0 to 0.10 wt. % titanium (Ti), and residual aluminum as well as inevitable production-related impurities, wherein the content of magnesium (Mg) and silicon (Si) fulfills the order relation 0.4 wt . ? % ? ? Si - 0.15 < wt . ? % ? ? Mg < 0.7 wt . ? % ? ? Si - 0.2 .

  • Patent number: 10214802
    Abstract: An aluminum alloy and a method for improving the ability of a semi-finished or finished product to age artificially, includes an age-hardenable aluminum alloy on an Al—Mg—Si, Al—Zn, Al—Zn—Mg or Al—Si—Mg basis, wherein the aluminum alloy is transformed to a solid solution state, in particular by solution heat treatment (1), is quenched and subsequently forms precipitations by a process of natural aging (3), the method involving at least one measure for reducing a negative effect of natural aging (3) of the aluminum alloy on artificial aging (4) thereof.
