Abstract
During the past forty years, a range of forged nickel–base alloys with progressively increasing strength and alloying complexity has been developed. They are used in a variety of arduous applications which demand the highest standards of billet integrity. Some of the possible manufacturing techniques are reviewed in this paper, along with the control of various defect types. To ensure quality and consistency of product integrity, a system of review and verification of process control data is outlined, along with the usual inspection and product testing techniques.
