Since its initial report in 1986 the science of ceramic superplasticity has steadily advanced. The observations of superplasticity in metals including aluminium magnesium iron titanium and nickel ceramics including monoliths and composites intermetallics including iron nickel and titanium base and laminates are thoroughly described. Save for later. The ceramic base materials made superplastic to date are based on the principles developed for metallic alloys and claims of observations of both types of superplasticity have been made for.

Superplasticity is reported in a wide range of materials for example metals and alloys including dispersion strengthened alloys ceramics metals as well as ceramics based composites nanostructured materials bulk metallic glasses and geological materials. Since then superplasticity has been extensively studied in metals.
