Description: This interactive animation present stress-strain curves for both commercial purity and Mg-alloyed aluminium. In comparison with 99.5% Al, the Mg solute allows very little dynamic recovery at room temperature, thus preventing dislocation rearrangement into a cell structure. Of course, since recovery is a thermally activated process, a cell structure can be produced in Al - 5%Mg by deforming at a higher temperature, e.g. at 400 °C. In this animation you can click on the micrographs to enlarge.
