| Abstract Scope |
The use of aluminum extrusion alloys in the automotive sector is increasing in response to the need for a reduction in the mass of battery electric and internal combustion engine vehicles. The microstructure of the material can be tailored by careful control of extrusion conditions. In the current study, the microstructure was varied by modifying the billet temperature and the extrusion ram speed. The mechanical properties were examined by conducting uniaxial tensile tests for naturally aged (T4) and artificially aged (T5) tempers. It was observed that the yield and ultimate tensile stresses were lower in the material with a smaller grain size but the ductility as measured by the true strain to fracture was similar for the T4 temper materials regardless of grain size, while in the T5 temper the alloy with the larger grain size had a lower true strain to fracture compared the smaller grain size. |
