Bulletin of Materials Science, 1984 Superplasticity is the phenomenon of extraordinary ductility exhibited by some alloys with extremely fine grain size, when deformed at elevated temperatures and in certain ranges of strain rate. To put the phenomenology on a proper basis, careful mechanical tests are necessary.

High Strain Rate Superplasticity in Microcrystalline and Nanocrystalline Materials
, 2000 Superplasticity has evolved to become a significant industrial forming process. The phenomenon of superplasticity is explored at high strain rates where it is economically more attractive.

Comments on theories of structural superplasticity
The various theories of structural superplasticity are examined with reference to published experimental data. It is demonstrated that there is no theory which is consistent with all of the results, although four theories predict very similar, and ...

The requirements for superplasticity with an emphasis on magnesium alloys
, 2016 Superplasticity is defined formally as a tensile elongation of at least 400% and a strain rate sensitivity of ?0.5. It is now well established that superplasticity occurs only in materials having very small grain sizes, typically less than ?10??m.

Mesoscopic superelasticity, superplasticity, and superrigidity
, 2012 Atomic-undercoordination-induced local bond contraction, bond strength gain, and the associated temperature (T)-dependent atomic-cohesive-energy and binding-energy-density are shown to originate intrinsically the exotic paradox of superplasticity ...

Modeling C540-C20 Fullerene Collisions
Reviews on Advanced Materials Science, 2018 Collisions of C20 and C540 fullerenes are studied in a wide range of velocities by means of classical molecular dynamics. The simulations show that the collision scenario strongly depends on the collision velocity of the fullerenes.
