Finite element modeling of superplastic forming of ideal and intentionally defected titanium alloy products for the purpose of non‐destructive control

Abstract

The work is devoted to the development of the production of three-layered hollows structures made of VT6 titanium alloy by means of superplastic forming (SPF). Based on the numerical results the pressure cycle was determined to satisfy the superplastic flow condition in the stiffening ribs and to minimize the forming time.
