Superplasticity of Alloys, Intermetallides and Ceramics [Paperback]

Superplasticity is shown to be a universal phenomenon inmaterials ranging from metals and intermetallics toceramics. Superplastic deformation facilitates theproduction of materials with specifically chosen properties.This is illustrated using the examples of Mg-, Al-, andTi-based commercial alloys, steels, and superalloys.Some of the strenghts of this book are: the broad range ofmaterials studied, the reduction of scientific results to aform suitable for the practitioner, a profound physicalanalysis of the phenomenon, a new approach to superplastictreatment as a kind of strain-heat treatment, thepresentation of new data on superplastic flow and onproduction techniques of micro- and submicrocrystallinestructures.Superplasticity is shown to be a universal phenomenon inmaterials ranging from metals and intermetallics toceramics.
