| Abstract Scope |
Accumulative roll bonding is a novel severe plastic deformation technique used to produce submicron-grained material through repeated stacking and roll bonding. This process has provided pathways for low temperature superplasticity in certain aluminum alloys, such as Al 5083.
Superplasticity is highly dependent on temperature, strain rate and starting microstructure. These parameters become increasingly important with submicron-sized grains, as grain growth must be avoided to realize low temperature superplasticity by means of grain boundary sliding. This work explores the relationship between microstructural stability, deformation temperature, strain rate, and the primary deformation mechanisms responsible for superplasticity during uniaxial tensile testing of Al 5083 produced by accumulative roll bonding. |
