摘要： A method of casting a metal alloy ingot, including the following steps: providing a one side open-ended mould including a plurality of sides and a bottom plate defining a mould cavity with a mould opening, the open-ended mould being pivotable around a horizontal rotational axis between a position so that the mould opening points upwards and a position so that the mould opening points side-wards or down-wards; positioning the open-ended mould such that the mould opening points side-wards or down-wards; providing a casting container with an upwardly positioned aperture; filling the casting container with molten metal for one casting operation; coupling the casting container to the open-ended mould so that the casting container is located below the mould while the mould opening points side-wards or down-wards; rotating the open-ended mould together with the casting container around the horizontal rotational axis for approximately 90° to 180° from a position whereby the mould opening points side-wards or down-wards to a position whereby the mould opening points upwards such that the molten metal is conveyed through the mould opening into the open-ended mould until reaching a desired thickness, whereby the molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.

摘要： Method for producing a vehicle component, in particular a motor vehicle component, in particular a B-pillar, including providing a first aluminum alloy and a second aluminum alloy. The second alloy composition substantially matches the first aluminum alloy composition. Performing a heat-treatment of the first alloy to increase the ductility of the first alloy. Performing a heat-treatment of the second alloy. The heat-treatment of the first alloy differing from the heat-treatment of the second alloy. Welding together the heat-treated first alloy and the heat-treated second alloy to obtain a composite part. Shaping the composite parts into a motor vehicle component. The motor vehicle component sub-region of the first alloy can be designed as a predetermined deformation region when a force is applied due to an accident to achieve a good combination of rigid regions for example forming a safety cell, and deformable regions forming a crumple zone for absorbing energy.
