摘要
Significant softening of Zr-based bulk metallic glasses (BMGs) can be seen in a hypoeutectic Zr-enriched composition, which brings about very high toughness (for the Zr55Cu35Al10 and Zr60Cu30Al10 BMGs) and tensile plasticity at room temperature (for the Zr70Ni16Cu6Al8 BMG). The unique features of such BMGs include the formation of multiple shear bands and harmonic alternating movements that can immediately accommodate concentrated stresses and avoid accidental catastrophic fracture.
