Abstract

Ein Energieabsorptionsbauteil für ein Fahrzeug zum Absorbieren kinetischer Energie durch Verformung unter Ausbildung einer zumindest abschnittsweise faltenbalgähnlichen Struktur, hergestellt aus einer Aluminiumlegierung des Typs Al-Mg-Si, ist dadurch bestimmt, dass die sich rechtwinklig zur Oberfläche des Bauteils erstreckende effektive Korngröße (gemessen in ST-Richtung) der Körner kleiner als 100 µm ist und dass das Gefüge des Bauteils zumindest weitestgehend nicht rekristallisiert ist und die Körner in den L-ST-Richtungen ein Streckungsverhältnis (L:ST) von mehr als 4:1 aufweisen.

Figure imgaf001
An energy absorbing member for a vehicle for absorbing kinetic energy by deformation to form an at least partially bellows-like structure made of Al-Mg-Si type aluminum alloy is determined by the effective grain size extending perpendicular to the surface of the member (measured in ST Direction) of the grains is less than 100 microns and that the structure of the component is at least largely unrecrystallized and the grains in the L-ST directions have an aspect ratio ( L: ST ) of more than 4: 1.
