Research abstract
The approach selected to address the development of High Strength Stress Corrosion Resistant Aluminum Casting Alloys is to use A201 and AA2139 as the base alloy and modify/optimize the composition use thermodynamic modeling . Reducing the susceptibility to hot-tearing will be achieved through the use incorporation of grain refiners such as dispersoid forming elements to control the dispersoid/dendrite precipitation characteristics and to improve fluidity. Appropriate precipitation, strength, and solidification simulations will be performed to support alloy design and production. Alloys will be produced and tested to determine the microstructures, mechanical properties, and resistance to stress-corrosion cracking. Results of this effort will be included in a thermodynamic database. The EFV water jet inlet housing or steering bucket will be produced using an alloy developed on this program.
