In the superplastic forming process (SFP), exceptional formability can be achieved. The formability in SFP is far superior when compared to traditional methods. Through SFP, the most complex shapes with high dimensional tolerance were formed. In this article, bi-axial superplastic forming was conducted after the rolling process on various percentages of silicon carbide composite (SiCp) particles in the gas pressure forming tester. Results of this study are mainly focused on finding favorable forming parameters (temperature, pressure, and time) for the superplastic formability of various Al/SiCp prepared by the stir casting process.
