Transition in Deformation Mechanism of AZ31 Magnesium Alloy during High-Temperature Tensile Deformation

Figure 10

SEM micrographs of the as-rolled specimens deformed during tensile tests at 573 K (a)–(d) and 623 K (e)–(h) at an initial strain rate of 3×10⁻³ s⁻¹, for tensile deformation ratios of 20% (a, e), 40% (b, f), 80% (c, g), and 120% (d, h). The tensile direction is along the vertical direction.
