Pristine & MWNT-reinforced alloys
FE-SEM images showing the surface morphologies of the pristine and 5 wt% MWNTs-reinforced magnesium alloy composites, respectively. The pristine magnesium alloy has more cracks compared to 5 wt% MWNTs/magnesium alloy composite. As shown in the right image, we can see the MWNT reinforcing the oxide layer. Credit: Appl. Phys. Lett.
