Ity in metals ceramics intermetallics and composites. 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.

Superplasticity in metals ceramics and intermetallics. University of california department of mechanical aeronautical and materials engineering davis ca usa 95616. A knowledge of fundamental issues in ceramic superplasticity has advanced to the stage that the technological application of superplastic deformation and specifically biaxial gas pressure deformation has now been demonstrated 74 75. Historically there has been no universally accepted definition for super plasticity.

Save for later. 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.

Superplasticity 6 1 introduction superplasticity is the ability of a polycrystalline material to exhibit in a generally isotropic manner very high tensile elongations prior to failure t 0 5t m 406.

This is the ability of certain materials to undergo very large tensile strains a phenomenon that has increasing commercial applications but also presents a fascinating scientific. Since then superplasticity has been extensively studied in metals. 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. The first observations of this phenomenon were made as early as 1912 407.
