Journal ArticleDOI
An evaluation of the strain contributed by grain boundary sliding in superplasticity
TL;DR: In this paper, it was shown that the experimental method used to measure the sliding contribution will lead to estimates in the range of about 45-90% even when all the deformation is by grain boundary sliding and the associated accommodation process.
Journal ArticleDOI
An investigation of grain boundary sliding in superplasticity at high elongations
TL;DR: In this paper, experiments were performed on the superplastic Zn-22% Al eutectoid alloy to determine the contribution of grain boundary sliding at both low (35%) and high (∼235%) elongations.
Journal ArticleDOI
The role of matrix dislocations in the superplastic deformation of a copper alloy
TL;DR: In this article, the densities of dislocations trapped in coherent twin boundaries may be used to provide a direct and quantitative comparison of the extent of intragranular slip in the three regions of behaviour associated with superplasticity.
Journal ArticleDOI
Microstructural evolution during initial stage of high strain rate superplastic deformation in powder metallurgical 7475 Al–0·7Zr alloy
TL;DR: In this article, the microstructural evolution which occurred during this initial deformation stage was examined, especially at high strain rates, showing an increase in m value, the subboundary misorientations and thus the contribution of boundary sliding tended to increase with strain.

Stereographic Analysis of Grain Boundary Sliding in Superplastic Deformation of Alumina-Zirconia Two Phase Ceramics
TL;DR: Grain boundary sliding during superplastic deformation has been investigated for fine-grained Al 2 O 3 -20%ZrO 2 (3 mol% Y 2 O3 doped ZrO2 ) ceramics prepared with no additive.
