Room‐temperature local structure changes in a bulk metallic glass, namely crystallization and void formation, occur after uniaxial compressive plastic deformation; probably this is due to the creation of free volume. Deformation‐induced nanocrystallization may provide a synthesis of bulk amorphous‐nanocrystalline alloys. The Figure shows a TEM image of voids in a bulk Zr55Al10Ni5Cu30 specimen prepared by standard twin‐jet electrolytic thinning followed by low‐angle ion milling.
