英文摘要	Mechanical reliability of metallic glass composites is an important performance affecting their engineering applications as structural materials. In this work, the reliability of shape memory bulk metallic glass composites was evaluated by coefficient of variation. The coefficient of variation of mechanical properties, especially the plastic strain was reduced more than 34% by 1 cycle mechanical training at 800 similar to 900 MPa or by 10 cycles at 600 MPa. The mechanism of enhanced reliability by proper mechanical training was revealed. These proper training treatments would provide more martensite nuclei, thus reduce the randomness of martensitic transformation and shear bands initiation. This investigation provides a method for improving the mechanical reliability of bulk metallic glass composites for the first time.
