Main Page | See live article | Alphabetical index Superplasticity is a phase where solid material is deformed beyond its usual breaking point. Such a state can be achieved as a result of high temperature and/or pressure. In a state of superplasticity, solid matter can exhibit certain hydrodynamic qualities without becoming an actual liquid. An example of this state is the behavior of the metal forming the lining of a HEAT round. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
