Abstract
In this paper is evaluated workability of rolled aluminium alloy based AIMgSi. Static tension test was used for obtained the mechanical properties, such as tensile strength, yield strength, elongation, the strain hardening exponent and coefficient of surface anisotropy. Rolled samples used for a tensile test were taken in three different directions, namely in the direction of rolling, in 45 ° and 90° direction. The result is an consideration of suitability of the material for stamping technology. For measurement of the elongation, variations in thickness and width in real-time was used method called videoextensometry. To obtain deforming maps and left side of forming limit diagrams (FLD) was applied digital correlation method (DIC).
Highlights
Al–Mg–Si alloys or EN AW 6000 series alloys are widely used for medium strength structural applications and in increasing demand in the automotive industry
Static tension test was used for obtained the mechanical properties, such as tensile strength, yield strength, elongation, the strain hardening exponent and coefficient of surface anisotropy
These alloys have been the materials of choice for skin panels because they have a combination of good formability and medium strength
