Abstract
The tendency for anisotropy and transient effects with deformation of the superplastic Pb-Sn eutectic alloy are explored by using tension/torsion and the tensile test. The development of anisotropy has been sensed in the torsion test and in tension followed by torsion test where an axial stress is detected during torsion deformation. Computation of stress vs non-elastic strain rate during tensile deformation under conditions of non-zero loading rate clearly show transient behavior, and results which are generally different from steady-state deformation conditions. These results imply that the constitutive models representing superplastic flow need further development to account for these complexities.
