Serrated flow in nanostructured binary Mg-Al alloys

(a) Engineering and true stress-strain curves at 2 × 10− 2 s− 1 of strain rate. Inset is a SEM image of a Mg-10Al micropillar after microcompression under strain rate of 2 × 10− 2 s− 1. (b) Zoom in the periodic region enclosed by a rectangle in (a) showing type B serrations.88
