Superplasticity

Abstract

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 and its origins surveyed. The salient features in the majority of the reported cases of superplastic behaviour in metals and alloys (and also certain ceramics) are included, together with a brief outline of some technological applications.
