Abstract : The present programme was intended to answer the following questions: How do natural flaws behave under typical service stresses; Which typical geometries of such flaws are present in large forgings; Under which conditions (size of the flaw, magnitude of stress) do such flaws propagate; How do small flaws bunched close together propagate; and How accurately is the actual size of flaws in the interior of large forgings indicated by ultrasonics.
