The two necessary conditions for superplasticity is higher temperature and low strain rate of deformation.

The two necessary conditions for superplasticity is higher temperature and low strain rate of deformation. Correct Answer True

The superplasticity is associated with high strain rate sensitivity of the material. This behavior is generally observed above 0.5Tm and at a very low strain rate.
