Superplasticity

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.

Superplastic-like flow in a fine-grained equiatomic CoCrFeMnNi high-entropy alloy

Materials Research Letters, 2017
A CoCrFeMnNi high-entropy alloy (HEA) showed elongation to failure ∼320% at T = 1023 K and a strain rate $ \dot \varepsilon = {10^{ - 4}}\, {{\rm s}^{ - 1}} $ .

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.
