Abstract
Theories of superplasticity are reviewed in this chapter in the following order. (a) Theories of structural superplasticity, (b) Theories of environmental/transformation superplasticity. The theories proposed from the former Soviet Union during 1945–1962 are often referred to as the early theories and those propounded since the mid-1960s are known to as the modern theories.

Late F.R.N. Nabarro pointed out to the first author (KAP) that this is a symmetry breaking problem, i.e. due to irregularities in local grain shape, fluctuations in stress etc. a plane interface gets formed first along one direction as indicated in Fig. 8.9b, which then precludes plane interface formation in an orthogonal direction. For further consideration, see, [1570, 1573].
