SFSA: PREVENTING BRITTLE FRACTURE

Prevention of brittle failures in steel castings has been the goal of a technical research program of the Steel Founders' Society of America. SFSA now recommends the results of its research involving the NDTT (Nil Ductility Transition Temperature) concept. A related project involves the relationship between fracture toughness and strength. SFSA sees this pointing toward a new design philosophy of not specifying an absolutely flawless metallurgical structure but enabling an engineer to predict whether or not a flaw of given dimension will cause brittle failure.
