摘      要：In this paper,the effects of different strain rate(1.10-5 s-1,5.10-5 s-1,1.10-4 s-1,5.10-4 s-1,1.10-3 s-1)and aspect ratio(1:1,1.5:1,2:1,2.5:1,3:1)on mechanical properties of Zr-based metallic glasses at room temperature were *** results indicate that as the strain rate increases,the plastic strain and compressive strength of the specimens gradually *** specimen with the strain rate of 1.10-5 s-1 exhibits the higher plastic strain of 10.25%,compressive strength of 2002 MPa and fracture strength of 1999 *** addition,accompanied with the increase in aspect ratio,the plastic strain of the specimens declines from 25.42%to 1.97%,meanwhile,the compressive strength and fracture strength of the specimens also present declining trend.
