Superplastic properties have been developed in Al-Li based alloys. Alloys produced both by ingot metallurgy (IM) and powder metallurgy (PM) are included. The influences of processing parameters leading to superplasticity are discussed and, in particular, the properties of Al-Li alloys produced by rapid solidification processes are described. Microstructural changes that occur as a result of thermomechanical processing are presented. In addition, room temperature properties have been measured in the solution-treated and peak aged (T6) condition for all the alloys and comparison is made with other commercial, non-lithium-containing, superplastic alloys. Emphasis is placed on properties of interest in aerospace applications such as specific modulus and specific strength.
