Abstract
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 properties ( design minimum tensile yield stress of 75 ksi). Therefore, only these two alloy systems will be examined in this program. To achieve the property goals, the concept of micro alloying will be employed. If successful, the new alloy/products will be evaluated by major aluminum rolling mills and extruders and forgers for its potential for full scale commercial implementation.
