hardening and high fracture toughness. Metallic glasses differ from traditional crystalline materials in that the atoms do not assemble on a crystalline lattice. Prior to the development of bulk metallic...) was required to prevent crystallization [1]. The development of bulk metallic glasses [2-3] enabled a wild range of mechanical tests including compression, torsion, fracture toughness and fatigue......
