Description

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.

Application of the Grain Boundary Internal Friction Peak to the Determination of Optimum Deformation Conditions of a Superplastic Alloy
