Fig. 1: High strength and ductility achieved in AX61 through rotary swaging and flash annealing.

a Engineering stress-strain curves of as-extruded (green solid line), rotary swaged (blue solid line), conventionally annealed (purple dashed line), and flash annealed (red solid line) AX61. AX61-FA exhibited substantially higher strength and elongation than AX61-EX and AX61-CA. b Engineering stress-strain curves of as-extruded (green solid line), rotary swaged (blue solid line), and flash annealed (red solid line) AZ31. AZ31-FA was almost similar as AZ31-EX in strength and ductility. c UTS and tensile elongation of AX61-FA compared with other rare-earth-free Mg alloys under various processing conditions (References of these data points are listed in the Supplementary Fig. 5).
