Structural, ballistic, and mobility requirements have led to the selection of aluminum alloy 2519 as the primary structural material for the Advanced Amphibious Assault Vehicle (AAAV). Two-year seawater alternate immersion exposures of welded AI 2519 panels with and without protective coatings were conducted to simulate the expected AAAV service environment.
Service life of any weapon system depends upon factors that impart long-term durability and robustness to its structure and subsystems, while sustaining its functional properties. The paper describes basic principles and guidelines on corrosion control and rules that could be easily followed to ascertain some specified service life and reduce total ownership costs.
The Hanford site contains approximately 55 million gallons of radioactive and chemically hazardous wastes arising from weapons production. This paper will present a Bayesian framework to model the probability of tank failures at Hanford and illustrate its use for tanks that are already known to have failed and leaked waste.
