Abstract
The grain boundary internal friction peak of a superplastic alloy, Al-2.7Li-1.2Cu-0.9Mg-0.14Zr (in wt%), is measured with a variable frequency pendulum. The Arrhenius line for the higher temperature edge of the peak is suggested to be used as a guide line for the determination of the optimum superplastic forming conditions (temperature and strain rate) of the alloy.
