Abstract Scope |
Magnesium (Mg) and Mg alloys are promising materials, particularly with applications in aerospace and automotive industries, due to their low weight, high specific strength, and the abundance of Mg within the earth’s crust and sea water. One challenge limiting the wider use of Mg and its alloys is their low ductility and early failure from shear banding. This research aimed to illuminate the characteristics of shear banding through observations made in hot-rolled, pure Mg specimens with varying grain sizes. Using in-situ optical imaging and post-deformation electron microscopy techniques, the shear banding and fracture behaviors in pure Mg were evaluated. The evolution of shear banding was also illustrated. A comparison of Mg with different grain sizes revealed the effect of grain size on the modification and suppression of shear banding. This research deepened the understanding of Mg deformation mechanisms and furthered the effort towards increasing its mechanical properties. |
