Environmentally Assisted Fracturing under Sustained Loadingern high strength steel rocket motor case is susceptible to SCC and hydrogen embrittlement cracking whereas cast iron and bronze canon were not. No reason is evident for expecting this pattern of increased threat of SCC to subside, and it may even spread.

Corrosion Fatigue Behavior of Coated 4340 Steel for Blade Retention Bolts of the AH-1 Helicopter a WC-coated bolt is expected to last over 3000 hours (the approximately design life of the airframe) as compared to about 300 hours for current Cd-plated new production bolts and about 500 hours for Cr-plated reworked bolts. Thus a significant cost savings has been projected if bolt reconditioning and replacement is eliminated.

Ductile Fracture Analysis and Safety of Nuclear Pressure Vessels catalyst to this development has been the discovery of radiation embrittlement in the ferritic steels used in pressure vessel construction. This chapter reviews current fracture analysis methodology for nuclear vessels from the viewpoint of linear elastic fracture mechanics and code procedures which are applied to assure structural integrity.
