Defects make metal stronger: aluminum alloy

Caption

Electron microscope image of the aluminum alloy from the study. The light gray areas are sections of traditional crystals within the aluminum alloy, while the black dots are sections where NIST found quasicrystals. Meandering black lines emanate from the quasicrystal sections. These lines are defects that break up the pattern of traditional crystals throughout the alloy, increasing its strength.
