- Abstract
- A study has been made on the superplastic deformation behavior of warm-rolled 6013 Al alloy. A series of load relaxation tests have been carried out on a warm-rolled 6013 Al alloy. They are well interpreted by grain boundary sliding (GBS) and grain matrix plastic deformation (GMD) using the internal variable theory of structural superplasticity. Uniaxial tensile testing shows a maximum elongation of 370% achieved at 560 degrees C under the initial strain rate of 1 x 10(-4) s(-1). These conditions of maximum elongation are consistent with the load relaxation results. (c) 2006 Elsevier B.V. All rights reserved.
