Abstract Scope |
In a complex structural assembly, such as in automobiles and in aerospace structures, a single part will often need to perform more than one function. For example, B-pillar in automobiles should have high strength to sustain high dynamic loads and large elongation for increased energy absorption so that the combination will lead to increased crash resistance. In this study, shear assisted processing and extrusion (ShAPE) was utilized to create tubes with high strength/low ductility and high ductility/low strength regions in 6061 Al alloys. The ShAPE formed tubes were subjected to hardness and tensile property investigation in as-extruded and peak aged conditions. For instance, in peak aged condition, yield strength of 200+ MPa was noted in the highest strength region while >10% total elongation was noted in other regions. Additionally, various electron microscopy techniques were utilized to investigate the underlying microstructural features responsible for such property variation. |
