- the invention has for its object a structural component to create which with extruded structural components achieved requirements with regard to crash behavior.
- Alloy used for structural components also for the production of body parts can be used.
- the structural component has a formed from sheet metal and part connected to a tubular part or hollow body.
- the tubular part is preferably rectangular in cross section, but can in principle have any cross-sectional shape.
- the tubular part is further expanded by hydroforming reshaped.
- connection of the sheet to a tubular part can be done by any Connection type, for example by welding, gluing rivets or screwing.
- the alloy used for the structural component can also be used for production of body parts, in particular in the form of a two-sheet structure such as a bonnet, Door and trunk lid of a passenger car are used, what is the scrap recycling or recyclability of structural components and body panels significantly simplified.
- the structural component is used as a safety part in vehicle construction, especially in the automotive sector.
- the alloy can be processed in the usual way by continuous casting or strip casting, hot and / or cold rolling to form sheet metal or strip.
- solution annealing is carried out in a continuous belt furnace in a temperature range from 520 ° C. to 580 ° C. with subsequent quenching. Quenching can be carried out in the usual way, usually with water or with air, depending on the sheet thickness.
- solution annealing care must be taken to ensure that all soluble constituents such as Si and Mg 2 Si pass into solid solutions and are in the supersaturated state after cooling.
- the cooling rate can have a significant effect on the mechanical properties, because Si and Mg 2 Si precipitate at the grain boundaries if the cooling rate is too slow and thus significantly deteriorate the crash and bending behavior. In addition, the hardenability and the corrosion behavior are impaired.
- the structural components and body parts are preferred in the heat-cured state, especially in the heat treatment state T6, used.
- This state of heat treatment can affect body parts generated during a paint baking cycle.
- the strips or sheets used are preferably in a thickness range from 0.8 to 4 mm.
- the strips and sheets can also be chemically treated before they are finished or pretreated electrochemically and / or with a dry lubricant coating be provided.

Solution annealing was carried out at 560 ° C. with subsequent quenching in water.
- the crash behavior was determined in a quasi-static compression test with notes rated from 1 to 3, with 3 being the top grade.
- the quasi-static compression test is used to assess energy-absorbing components.
- the wished Behavior is characterized by regular folding without Cracking.
- the appearance of the compressed samples was compared with the Notes 3 (no cracking, even folding), 2 (roughened, slightly torn), and 1 (crack formation).
