Abstract :
Analysis of energy dissipation during shear-banding aids to understand plastic deformations of bulk metallic glasses (BMGs). For Zr55Al10Ni5Cu30 BMGs at 298 K, multi-step shearing is proposed, and the thermal energy during serrations cannot result in a temperature rise (ΔT) higher than Tm. At 77 K, N-step shearing is supposed. When N is in the range of 24–47, it is reasonable to deduce the resulting temperature from 0.8Tg to Tm, accompanied by a continuous plastic deformation.
