Abstract Superplasticity is the ability of some materials to undergo very large, irreversible, tensile elongations without necking and failing. Generally, a very fine grain structure is required (a typical grain size will be of the order of 1 μm) and a deformation temperature of about 0.5 Tm is necessary to enable the appropriate ...

Strong and superplastic nanoglass
Nanoscale, 2015The strength-ductility tradeoff has been a common long-standing dilemma in materials science. For example, superplasticity with a tradeoff in strength has been reported for Cu50Zr50 nanoglass (NG) with grain sizes below 5 nm. Here we report an improvement in strength without sacrificing superplasticity in Cu50Zr50 NG by using a bimodal grain size ...

The superplasticity phenomenon, which is characterized by a metal's capacity for a large degree of relative uniform extension, is reviewed for the purpose of assessing both its potential applicability to practical metallurgical operations and the possible benefits to be derived from further research and development.

The theoretical maximum tensile strain--that is, elongation--of a single-walled carbon nanotube is almost 20%, but in practice only 6% is achieved. Here we show that, at high temperatures, individual single-walled carbon nanotubes can undergo superplastic deformation, becoming nearly 280% longer and 15 times narrower before breaking.

The phenomenon of superplasticity, where metals deform extensively under small forces and without risk of fracture, is no longer a scientific curiosity. Current studies range from aspects involving metal physics and extend through to areas of industrial application such as metal-working. and fabrication. In the present review superplasticity is defined

Mechanics of Superplastic Deformation and Assessment of Superplastic Behavior
2018Scientific investigations on Superplasticity started with the works of Bengough [494], the scientists at the old Kaiser Wilhelm Institute in Berlin and Pearson [28], all from the early years of the twentieth century.
