文摘

Fracture morphology and micro-indentation behavior is studied. The smaller BMG sample exhibits the larger plasticity. Microhardness and density increase with decreasing the cooling rate. Formation of shear bands has been reported in deformed specimens. Structure and mechanical properties of BMGs can be controlled by the cooling rate.
