Investigation of the effect of thermo-mechanical processing orientation on the final material performance in 6xxx aluminium alloys produced with high recycling rates

Recycling of aluminium alloys is crucial due to its effects on environment, economy and social situations. It is also a popular research topic for aluminium producers and aluminium end users like automotive industry due to its tremendous effects on final carbon equivalent value and price. This scientific study emphasizes the critical importance of recycling in alloys used in the automotive sector, investigating the effects of thermo-mechanical processing orientation on the final material performance of 6XXX aluminium alloys with high recycling rates. Specifically, materials obtained using high recycling rates on 6063 and 6082 alloys produced for the automotive industry have been examined. The study aims to evaluate the mechanical properties of materials under thermal load through methods such as anisotropic strength correlations and bake-paint testing. The central focus of the study is to establish correlations between mechanical properties in different orientations based on thermal inputs. Data obtained through mechanical tests and bake paint tests conducted at 0, 45, and 90-degree orientations to extrusion direction play a crucial role in determining the material's performance. The findings contribute to our understanding of the impact of 6XXX aluminium alloys produced with high recycling rates on the final material performance in industrial applications.
