A process for positioning at least one defect in a billet being forged into an
article is described. The size and location of the billet is first determined,
using a non-destructive test such as ultrasonic inspection. The movement of the
defect under selected forging conditions is then predicted, using a finite element
analysis model. The billet can then be positioned and forged under conditions which
cause the defect to move to a non-critical area of the article. In this manner,
a billet which might otherwise be discarded or set aside can often be retained
for a useful purpose. Related articles are also described.
