Characterization of Superplastic Deformation Behaviors of 7075 Al Alloy
초소성 7075알루미늄 합금의 변형특성 평가
Abstract
The superplastic deformation behaviors of 7075Al alloy have been characterized experimentally and analyzed by the internal variable theory of inelastic deformation. A simple rheological model including the grain boundary sliding has been used to interpret the superplastic deformation behaviors. A series of load relaxation and tensile tests have been carried out for 7075Al alloy at the various temperatures. The superplastic deformation of 7075Al alloy is confirmed to consist of the grain boundary sliding and accommodating grain matrix defprmation.
