This paper studies the influence of strain rate during superplastic forming on microstructure evolution Ti-4Al-3Mo-1V titanium alloy. The finite elements simulation (FES) process at a temperature 875 °C, which considered to be optimum this alloy, and constant uniform gas pressure 0.4, 0.7, 1 MPa were performed. response across formed part via FES each applied was analyzed. using same condition FES, time, performed lab machine. In initial state before forming, studied alloy exhibits mixture lamellar equiaxed grain structure. after for investigated. It observed that significantly affects uniformity thickness profile forming.
