Abstract
Amorphous alloys containing nanoscale crystals have been deformed in s itu in a high-voltage electron microscope. Acceleration in the nucleat ion and growth of nanoscale crystals has been found at a crack tip dur ing ageing under stress. It has also been revealed that the nanoscale crystals are free from lattice defects after deformation to cracking. These observations suggest that the presence of non-deformable nanosca le crystals plays an important role in the strengthening of amorphous alloys.
