Abstract
Powder forging processing of rapidly solidified aluminum alloys has benefits of excellent material properties attained by rapid solidification process and of high production efficiency of PM parts. In this study, powder forged Al-Si and Al-Fe base alloys were prepared using double action forging press and the mechanical properties were examined. In this process, it is possible to conduct two steps of compaction and deformation of preforms in one shot. It was confirmed that the mechanical properties of Al-Fe base alloy powder forged by double action forging press has good mechanical properties as of the extrusion. The double action forging give good metallurgical bonding between powders by efficient dispersion of surface oxides even the amount of plastic deformation is relatively low.
