To develop alternative materials for AL-Be alloys, ATI is going to utilize metal matrix composite technology alloys to match the key physical properties of AlBeMet 162.

Aluminum alloys are known to suffer from Stress Corrosion Cracking(SCC). SCC of high strength alloys can proceed rapidly, and can lead to devastating structural failures. However, a solid understanding of combined interactions of metallurgical, environmental and mechanical factors surrounding the… More

This program is to develop multi-layered,light weight armor alloys systems that offer improved fragmentation and armor piercing performance as compared to any other monolithic structures. Such alloys and laminated configuration will be developed by utilizing advanced computational techniques to… More

Two different approaches will be investigated for producing aluminum alloys with a layer structure that have mechanical properties similar to Al 7050-T7 and Al 7075-T6 and greatly improved corrosion resistance. Layered aluminum alloys will be produced using the Novelis-FusionT casting process. … More

The objective of this program is develop high strength aluminum alloys ( as high strength as that of 7075-T6) that would not require anodization to achieve corrosion resistance. Among the Al alloy systems, only 7xxx and Al-Cu-Li alloy systems are capable of such a high strength level of 7075-T6… More

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… More

This program will focus on developing and validating computational models for near-net shape processing of aluminum alloys. Computational models will be developed for deformation modeling and for texture generation. Characterization of two aluminum alloys including flow stress, forgeability, and… More
