Abstract
Friction Stir Processing (FSP) is a solid-state thermomechanical processing technique that enables local grain refinement, densification, and homogenization of microstructure in metallic components. Here, FSP is applied to thin sheets of high-pressure die cast AM60 to address the porosity and heterogeneities inherent to the casting process. In this work, microstructure characterization is correlated to improvements in the static mechanical properties of the Mg-Al-Mn alloy system at various FSP processing conditions. Notably, there is a significant increase in the ductility and ultimate tensile stress of the system following FSP. The dominant deformation mechanisms for the as-cast material and the FSP material are investigated. Finally, the improvement in mechanical properties is discussed with respect to implications on fatigue life improvement in future work.
