摘要：
The compressive deformation of the Zr55Cu30Al10Ni5 bulk metallic glass (BMG) was investigated in the supercooled region. It was found that the deformation behavior of the BMG alloy is strongly dependant on strain rate and temperature. The BMG exhibits Newtonian behavior at low strain rate but becomes non-Newtonian flow at high strain rate. The correlation between flow stress as well as strain rate and temperature was established in terms of stretched exponential function.
