【 摘 要 】

The current report summarizes work performed on the project over the past calendar year (2001). The work concentrated on four areas: the fracture of AISI 4340 steel simulating weld heat-affected zones in DOE liquid waste storage tanks, investigation of the passive state on nickel, which is commonly used for containing highly alkaline solutions, development of a new theory for the transient growth of passive films on metals in contact with aqueous solutions, and exploration of the passive state on iron, because it is passivity that allows iron-based alloys to be used to contain DOE's liquid waste. Fracture of AISI 4340 steel in concentrated sodium hydroxide solution has been monitored by measuring the coupling current that flows between the crack and the external surfaces.
