Defects in the forged structure

Defects can occur in the forged structure if radii on the shaped part are too tight or if the parting plane of the die has been wrongly chosen. An inadequate choice of deformation rate can also easily lead to recrystallisation and thus to microstructural damage.

The forged structure depends in a complex manner on the geometric shape, the tool design, the parameters of the forging process and the type of feedstock, its alloy composition and plasticity.
