摘要：

Superplastic properties have been developed in Al-Cu-Li-Mg-Zr alloys. The alloys have low Zr levels ( less than equivalent to 0. 2 wt pct) and are experimental compositions originally designed as low-density, high-modulus, and high strength alloys for room temperature aerospace structural applications. The alloys have been manufactured both by an ingot metallurgy and a powder metallurgy (PM) route involving rapid solidification. After manufacturing, the alloys are not superplastic but require further thermomechanical processing. The microstructural changes that occur are described. Superplastic properties have been evaluated as a function of temperature, strain rate, and processing history.
