====== Superplastic forming ======
  * Superplasticity is a state in which a material is deformed well beyond its usual breaking point (high T, ultra low strain rates).
  * Multisheet superplastic forming of a self-stiffened titanium structure (Sonaca).
  * When pressed together, sheets got welded dur to diffusion bonding.
  * Optimal pressure cycle is computed in order to stay below a given plastic strain rate.
