Description
Mechanical deformation is expected to be an alternative route for synthesizing nanocrystalline/amorphous matrix composites. However, it is found that nanocrystalline/amorphous Al90Fe5Gd5 composites produced by cold rolling have lower hardness than the as-spun, fully amorphous, alloy. Much smaller pileups are observed around indents in rolled samples than in the as-spun sample. Combining high-resolution transmission electron microscopy with Fourier transform and image filtering, many nanovoids are observed in the shear bands near the boundary with the undeformed matrix
