Ionic mobility and superplasticity in ceramics
Superplasticity and superionic conductivity (SIC), both thermally activated processes, have been independently observed in certain materials with a high diffusion coefficient in high temperature ranges. Intuitively, this observation leads one to the idea that both types of behavior may be …

Transformation-superplasticity of metals and metal matrix composites
The work covers transformation superplasticity of metals, alloys and metal matrix composites. Fundamental studies of transformation superplasticity in unreinforced metals, which either deform plastically or by creep, form the basis of further investigations in metal matrix composites. Experiments …

Friction stir processing for superplasticity and other applications
… discovered including the area of friction stir superplasticity. Using the small grain size achieved by the process and the high grain boundary mis-orientation angle, it has been found that friction stir processing is capable of creating high strain rate superplasticity in aluminum alloys. This …

Low and Structure at Constant Temperature in a Superplastic Fe-Al-Mn-C Alloy.
Micrograin superplasticity is that property of some metals to elongate many times their original lengths during deformation at elevated temperatures. Micrograin superplasticity is exhibited during deformation at constant temperature by metals having a fine grain structure and is to be distinguished …

An investigation of the mechanical properties of warm rolled aluminum-17.5 weight percent copper alloy
… temperature properties as well as the onset of superplasticity at elevated temperatures. Ductility and toughness were increased almost six-fold, despite slightly decreased yield strength and maximum compressive strength. It would appear that warm working can be used to enhance both room …
