General advantages of high-speed forming

Twinning effect

Twinning effect in the lattice structure of the metal, with the constant reshaping resulting from a shearing of the crystal lattice from one position into another. In contrast to that, conventional forming produces the effect that the atomic rows within the individual crystals shift and the linkage of the atomic rows takes place on the next following lattice site.


Plasticity of several titanium and aluminum alloys can often only be achieved with the help of high speed. High-speed forming completely avoids the typical fissuring in the surfaces.

Sequence of effects

The sequence of effects of high-speed forming shows a “turn-up effect” which – similar to ‘active hydromechanical forming’ – leads to strain-hardening and thus increases the rigidity of the part.
