Abstract:Fine-grained titanium6Al-4V alloy, which typically has a grain size of about2μm, can be made to superplastic form at around800℃. The normal temperature for superplastic forming (SPF) with conventional titanium6A1-4V sheet material is900℃. The lower temperature performance is of interest to scientists because it can be exploited to achieve significant cost savings in processing by reducing the high temperature oxidation of the SPF dies, improving the heater rod life for the hot presses and increasin...
