This study investigates the optimization of superplastic forming in aluminum alloy 6061 reinforced with 100 nm silicon carbide (SiC) nanoparticles, fabricated by use of the ultrasonic cavitation technique. The formed composite was subjected to superplastic forming tests, achieving a maximum dome height of 21 mm. Key parameters, including pressure 2 MPa, 4 Mpa and 6 Mpa, temperature (560°C, 580°C and 600°C), and time 15, 30, and 45 minutes, were systematically varied. To identify the optimal process parameters, a Taguchi L9 experimental design was employed, facilitating a comprehensive examination of these factors' effects on the forming performance. The findings provide valuable insights for enhancing the superplastic forming process in aluminum-SiC composite materials.
